Solution 18.3.8 from the collection (workbook) of Kepe O.E. 1989

In this problem, it is necessary to determine the modulus of force F, which must be applied to a handle of length l = 0.2 m in order to lift a load weighing 4·103 N using a winch having a worm gear ratio of 50. The radius of the drum is r = 0.12 m.

To determine the required force F, we use the formula:

F = (Mг + Mп)·g / r·η

where Mg is the mass of the load, Mn is the mass of the lift (equal to zero in this problem), g is the acceleration of free fall, r is the radius of the drum, η is the gear ratio.

Substituting known values, we get:

F = (4·103 N)·9.81 m/s² / (0.12 m)·50 F ≈ 6.55 N

Thus, to uniformly lift a load weighing 4·103 N using this winch, it is necessary to apply a force F equal to approximately 6.55 N to a handle 0.2 m long.
