How to make Quick Mayonnaise

Homemade mayonnaise

Mayonnaise is getting expensive these days. I know you have heard you can make it on your own at home. It is true, I have tried it and it worked.

Ingredients you need to make your homemade mayonnaise

  • Vegetable oil
  • One egg
  • Pinch of salt
  • Sugar to taste
  • Lemon/vinegar

Vegetable oil should be of good quality, canola oil, Avocado oil, soya oil and the normal vegetable oil will work.

The egg should be fresh and of good quality otherwise mayonnaise will not form. Note that it is the egg and oil that forms the mayonnaise. The rest ingredients are just to give taste/flavour and preserve.

Just a pinch of salt. 

You can add sugar to taste. 

2 teaspoons of either lemon or vinegar juice should do. It adds flavour and preserves the mayonnaise.

Equipment you will need

  • Blender/mixer

Any blender or mixer will do. 

Procedure of making Mayonnaise (Using a blender)

Put the egg, pinch of salt, two teaspoons of lemon or vinegar Into the blender jar and cover it. 

Set the machine to the lowest setting then mix. 

Next open the hole provided within the cover of the blender jar, switch on the blender then very slowly pour the vegetable oil into the jar as it mixes.

The sound of the blender will change when the mixture has thickened. That is your homemade mayonnaise.Switch off the blender. Store the mayonnaise in a bottled container and use within 24 hours.

[Optional] You can also add two or more teaspoons of sugar to the mayonnaise and mix for two seconds in the blender if you like.

How a Car Engine Works

car engine showing pistons and crankshaft

The piston

The piston is the powerhouse of the car engine. The piston moves up and down. When the piston travels to the end of its range whether up or down, it is called a stroke.

A car engine is equipped with 4 or more pistons. The movement of these pistons is transferred to the wheels of the car which enables it to move.

For car engines, 4 strokes usually completes the engine circle enabling power to be transmitted to the wheels. 

exploded view of a car engine

The four stroke cycle, how it works.

First stroke; intake.

 The piston descends, sucking an air-fuel mixture into the cylinder .

The valves open allowing fuel – mixture into the cylinder

2nd stroke; compression

With all valves closed the piston comes back up,  compressing the fuel and air  mixture 

3rd stroke ; internal combustion

An electrical spark from the spark plug ignites the compressed fuel and air mixture inside the cylinder causing an internal combustion. The resulting combustion forces the piston to the bottom of the cylinder again.  A connecting rod transfers 

this power to the crankshaft which in turn transfers power to the wheels which enable the car to move.

4th stroke; exhaust. 

The piston comes back up,  pushing the burnt fuel and air  mixture out through the

open exhaust valves and the exhaust port.

The pistons and connecting systems

For smooth power delivery,  A car uses at least 4 pistons. These pistons take turns to fire the engine.

 Camshafts  are  specially shaped 

cams that  push spring-loaded valves open in turn.  

Cam gears and a timing belt or chain 

links everything to the crankshaft.  The crankshaft translates piston power from the engine to the wheels.  

It has counterweights to balance against the 

pistons for perfectly smooth revolutions.

The engine block holds the crankshaft 

and cylinders, and the cylinder  head holds valves, ports, cams, etc.

A geared flywheel sits at one side of the  

crankshaft for connection to a transmission.

The basic car engine has four cylinders 

arranged in a single row.  But there are many other possible configurations, including six, eight and 12 cylinders.

 Systems that support the internal  combustion process.

Air intake system

Air comes in through an air filter,  and then into the intake manifold where it mixes with fuel before being sucked  into individual cylinders through intake ports.

Fuel injection system

The fuel pump carries gas from the tank,  through a fuel filter, to the engine 

where fuel injectors emit a precisely 

timed spray of gas into the intake port.

Cooling system

Engines get very hot during operation  and 

require a cooling system. The cooling system  basically consists of a radiator, water pump and cooling channels. Cool water from the radiator is pumped through cooling channels that go around the hot cylinder blocks, cooling the engine in the process. This hot water then passes through the radiator and is cool again for recirculation.

The radiator has a network of small tubes and fins. As hot water passes through these tubes it is cooled with the aid of fins and radiator fans.

Electrical system

This is a complex system that basically consists of the battery, fuses, wiring , coils, spark plugs, and the alternator.

The battery provides the initial electrical connection that enables the car to start. The alternator is like an electric generator. Once the car engine starts running, the alternator basically charges the battery and generates the electricity required for the whole car to function properly

 lubricating system

Just like the cooling system, the engine lubricating system basically consists of , engine oil, oil storage,  oil lubricating channels, oil filter and oil pump.

The oil pump keeps oil properly 

pressurized and flowing.

It pumps the motor oil  to lubricate, cool,  clean, prevent corrosion of the engine.

The oil filter keeps oil clean from contaminants.

Exhaust system

The exhaust manifold collects gases 

from multiple cylinders into one pipe. 

Exhaust flows through the catalytic converter, which captures toxic chemicals in engine exhaust. And then out through a muffler that reduces exhaust noise.

How to Calculate Design Load of a Concrete Slab (factored)

In reinforced concrete design , there is what is called the factor of safety. The factor of safety is multiplied by the calculated load of the structural element. This is done to reduce the possibility of the structural element failing under its actual, or expected loadings.

When the factor of safety has been applied to the calculated load of a structural element, it is called design load. Note that Factored load is also the same as design load.

Determining the Design (factored) load of a Concrete Slab.

The formula for calculating the design load of a Concrete Slab is:

1.4gk + 1.6qk.


gk= dead load

qk= live load

1.4= factor of safety applied to dead load

1.6= factor of safety applied to live load.

Dead load is the same as the weight of the concrete slab element. 

Live load is the movable or variable load the slab will carry such as people, furniture,machinery and so on. 

The unit of the design load will be in kN/m².

The weight of concrete used in reinforced concrete design calculation is 24kN/m³

Example 1 calculating design load of slab

concrete slab panel

Let’s say a concrete slab panel is to be designed for a private dwelling. It  has a depth ( thickness) of 0.2m, a length of 5m, and a width of 3m as shown above, the design load can be calculated as follows:

The dead load of the slab panel is the weight of concrete multiplied by the slab thickness.

That is,

24kN/m³ × 0.2m = 4.8kN/m²

Therefore gk = 4.8kN/m²

Live loads for buildings are standardized. In page 2 of BS 6399 part 1, the live load for private dwellings is 1.5kN/m² (shown below)

Table minimum imposed floor loads.BS 6399 part 1

Therefore qk= 1.5kN/m²

Design load= 1.4gk+1.6qk=( 1.4×4.8kN/m²) + (1.6×1.5kN/m²) = 6.72kN/m² + 2.4kN/m²


Example 2. calculating design load of slab

Looking at part of a floor plan shown below, we will be calculating the design load for the floor plan labelled P8 as shown.Take live load for private dwellings as 1.5kN/m².

Part of general floor arrangement plan of a proposed building


The depth of the slab panel is 150mm or 0.15m

We know that the formula for  design load of slab panel is  1.4gk + 1.6qk and weight of concrete is 24kN/m³

Dead load, gk, = weight of concrete multiplied by panel thickness= 24kN/m³ × 0.15m = 3.6kN/m²

Live load , qk=1.5kN/m². (page 2 of BS 6399 part 1)

Design load is 1.4gk + 1.6qk=

(1.4×3.6kN/m²)+(1.6×1.5kN/m²)= 7.44kN/m²

Slab Design load is used for the calculation of the amount of steel reinforcement required for the slab panel.

Manchester City for the Title after Liverpool Draw

The title is still Manchester City’s to lose with 7 games to go after forcing Liverpool to a 2-2 draw. Indeed City should have won the match if they had converted more of their chances. City on 74 points lead Liverpool by one point meaning their fate is still in their own hands.

Elsewhere Chelsea walloped Southampton by 6-0 to sit comfortably in 3rd place with 63 points.

Tottenham Hotspur complete the top 4 after their 4-0 trashing of Aston Villa and Arsenal falling at home by 1-2 to Brighton.

Brighton on the other hand have boosted their chance of survival with that wonderfully victory.

Manchester United failed to spark as they lost out by 0-1 to Everton in a tense affair. They are 7th in the league table currently with 51 points

Everton are 4 points off the drop zone while, Burnley, Watford, and Norwich are doomed for relegation.
