When lifting a load weighing 260 N using a movable block, they acted on the rope with a force of 136 N. What is the weight of the block?
Data: Pg (weight of the lifted load) = 260 N; F (effective force) = 136 N.
To determine the weight of the mobile unit used, we apply the formula: F = P / 2 = (Pg + Pb) / 2, whence Pg + Pb = 2F and Pb = 2F – Pg.
Let’s calculate: Рb = 2 * 136 – 260 = 12 N.
Answer: The weight of the movable unit used is 12 N.
