This is to introduce high school students to the rigours of engineering, to let them see what the real world of engineering is about. If they are interested in engineering, or just sampling different fields, this is written just for them!
Let's start with "Torque required to raise load?"
This would be where the energy required to raise a load is based on the ability of the machine to perform by combustion to do the things required, because of the load, like a car frame that is supposed to go forwards - how much energy is required to make it move? How much energy per meter, or, more conventionally or usually, how much energy is needed to move for each kilometre?
The formula;
Let's skip to the brackets on the left? This would be where pie divided by pie equals one, [u] divided by [u] equals one, [d] and [m] divided by [d],[m] and [l] equals [m] and [l] so the answer for the brackets is three [4].
Then [d * 1.5] because [1F2D / 2] because the [m] is to the power of [d] equals [1d] * [1m] into the same thing in [d] equals [2d], yes? So the answer here is [1.5].
Multiplying [1.5] by [4] equals [6] or six, so the answer is to raise the torque by six times the load - there is six times as much energy required as mass to 'carry the load,' of course.
