The work done in lifting 30kg of bricks to a height of 20m on a building under construction is?
The work done in lifting an object can be calculated using the formula ( W = mgh ), where ( W ) is the work done, ( m ) is the mass (30 kg), ( g ) is the acceleration due to gravity (approximately ( 9.81 , \text{m/s}^2 )), and ( h ) is the height (20 m). Substituting the values, ( W = 30 \times 9.81 \times 20 ), which equals 5886 Joules. Thus, the work done in lifting the bricks is 5886 Joules.
A 60kg platform is 8m wide supported by 4 legs each of which are 2m from the edge of the platform What is the force on the left legs if a 30kg mass is placed on the left edge of the platform?
This problem asks to solve for unknown forces when an object is in equilibrium. Let us solve it! As platform is in equilibrium , so , by 1st condition of equilibrium, Upward forces = Downward forces T1+T2=600+300=900N , Now apply second condition, Anti-clockwise torque= Clockwise torque (taking point of first leg as axis of rotation so that torque due to T1 is zero) 300*2+T2*4=600*2 600-1200=-T2*4, 600=T2*4, or T2=600/4=150N ,now T1=90-T2=900-150=750N
How much one fifths are in 30kg?
To find out how many fifths are in 30kg, you first need to determine the value of one fifth of 30kg. One fifth of 30kg is calculated by dividing 30 by 5, which equals 6kg. Therefore, there are 6kg in one fifth of 30kg.
How many bags of concrete make up a square yard?

How do you convert 1 ton of scaffold into cubic meter?
To convert 1 ton of scaffold into cubic meters, you need to know the density of the scaffold material. Once you have the density in kilograms per cubic meter, you can convert the weight in tons to kilograms and then calculate the volume in cubic meters using the formula: Volume (m^3) = Mass (kg) / Density (kg/m^3).
What does 30kg equal in weight?
30kg = 30kg.
What is 3 tenths of 30kg?

Is a tiger 30kg or 300kg?
Honey, a tiger is definitely not 30kg, that's like saying a Big Mac is a health food. A fully grown tiger can weigh up to 300kg, which is basically the weight of a small car. So, if you see a 30kg tiger, you might want to run because that's one skinny cat.
What is 75 percent of 30kg?
That would be 22.5kg.
