Torque

Torque is the rotational equivalent of linear force in physics and mechanics. Based on the course of study, it is also known as the moment of force, rotational force, or turning effect.

Question

painter wishes to know whether or not he can
safely stand on a ladder. The ladder has a mass M₁ = 10
kg which is uniformly distributed throughout its length L
= 6.1 m. The ladder is propped up at an angle theta =
610. The coefficient of static friction between the ground
and the ladder is mus = 0.31, and the wall against which
the ladder is resting is frictionless.
0
Calculate the maximum mass of the painter for which
the ladder will remain stable when he climbs a distance
d = 3.9 m up the ladder.
If the painter does not stand on the ladder, what is the
minimum angle theta for which the ladder will remain
stable?

A fence post of mass m = 8 kg supports a fence with three lengths of barbed wire. The bottom wire is a distance d = 0.35 m from the ground and each wire is a distance 0.35 m above the previous one. Each of these three wires has the tension on it. For this problem, assume that the force exerted by these wires is purely horizontal. An additional guy wire is used to keep the pole upright with a tension of Fa = 490 N. The guy wire attaches to the post at a point h = 0.86 m above the ground and makes an angle of θ = 45 with respect to the horizontal. Write an expression for the tension in any one of the three fence wires. What is the normal force that the ground exerts upward on the post?
