the second one please
35 N POD31Prob#1) Net Torque 30N Calculate the net torque about the axle of the wheel shown below. Assume that a friction torque of 0.40 m N opposes the motion. Is the object going to roll clockwise or counter clockwise? 13 10 20 cn 20 N POD31 Prob#2) Static Equilibirum A sign is suspended by a cable and a rigid beam, as shown in the figure to the right. It is obviously an important (and factual) sign. The sign has a mass of 50 kg. The bar has a mass of 10kg. Determine the tension in the cable. Physics is awesome.Explanation / Answer
here,
theta = 30 degree
mass of sign , m1 = 50 kg
mass of bar , m2 = 10 kg
let the tension in the cable be T
taking moment of force about the hinge
T * l - m1 * g * l - m2 * g * l/2 = 0
T - 50 * 9.81 - 10 * 9.81 /2 = 0
solving for T
T = 539.6 N
the tension in the cable is 539.6 N
