What force must be applied to lift a 20 kg load on a stationary block?

Since a stationary block does not give a gain in strength, but only allows changing the direction of the action of the force, the following relation is true:
F = Ft (gravity) = m * g, where m is the mass of the load being lifted (m = 20 kg), g is the acceleration of gravity (we take g = 10 m / s2).
Let’s calculate the required force to lift the load:
F = m * g = 20 * 10 = 200 N.
Answer: To lift a load weighing 20 kg, you must apply a force of 200 N.
