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.

The drawing shows a uniform horizontal beam attached to a vertical wall by a frictionless hinge and supported from below at an angle 0 = 40° by a brace that is attached to a pin. The beam has a weight of 340 N. Three additional forces keep the beam in equilibrium. The brace applies a force P, and the hinge applies a force with a horizontal component H and a vertical component V. (a) Draw the free- body diagram showing the forces that act on the beam. Find the magnitudes of the forces (b) P, (c) H, and (d) V. Beam Hinge Pin Ꮎ Brace E

Q4.2. A springboard-type diving board is built from high grade aluminum. This particular board has a mass of 65 kg and is 3.85 m long. 33.8 cm wide, and 5 cm thick. (Aside: Most springboards start thick on one end, then get thinner as it moves to the other end. For this problem, assume the springboard has a constant thickness) One end of the springboard is attached to a hinge. The hinge lets the springboard move up and down, but keeps it from sliding out of place. 1.1 m away from the hinge, the springboard rests on (but is not attached to) a fulcrum. A diver with a mass of 65 kg stands on the far end of the springboard (opposite from the hinge), ready to begin their dive. Hinge Fulcrum Note: the measurements for this problem were taken from the springboards used in the 2016 Summer Olympics, 3 m Springboard event.
17 kg uniform store sign is held from a uniform horizontal beam as shown. There is a cable attached to the right edge of the beam and is secured to the wall, 250 cm above where the beam meets the wall. The sign is symmetrically suspended by two cords, the left cord being 80 cm from the wall, and the cord on the right being at the right edge of the beam, 200 cm from the wall. a. What is the tension in the left and right cords that hold the sign? b. What is the tension in the cable? c. What is the horizontal component of the force that the wall exerts on the beam?

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?
