A block system is used to lift a load weighing 50 N. Indicate what force should be applied.

It is known from the condition that a system of blocks is used to lift a load weighing 50 H. Find what force we need to apply for this to lift a load weighing 0.25 tons. (the condition is not given in full, a similar problem was found on the Internet).

Let’s start by writing a short summary of what is given:

P2 = 50 N;

m1 = 0.25 tons (let’s translate the weight of the cargo in kilograms) = 250 kg.

To find:

F =?

To find the force to be applied, apply the formula:

F = (P1 + P2) / 2 = (m1g + P2) / 2 = (250 kg * 10 H / kg + 50 H) / 2 = 1 275 H = 1.275 kH.
