Solution : the problem can be solved by balancing the torque about the hinge point.....
Torque = r x F
Here force is mg where m is the mass of the object. Now equating .. torque of force on the left = torque of forces on the right
We get
10 x 0.8 x g = 2 x 0.2 x g + m x 0.4 x g + 1.2 x 5 x g
So m =( 8 - 6-0.4)/ 0.4 = 4 kg

A chandelier with mass m is suspended from a cable with mass M from the ceiling. Take a Y-axis vertically up and apply Newton's 2nd law to find the magnitude of the tension at the top and at the bottom of the rope. Treat the weight w of the chandelier and the weight of the cable W as given. Draw a free body diagram for both the rope and the chandelier.

An aluminum cable with cross-sectional area 1.50 times 10^-6 m^2 is suspended from the ceiling. A mass is suspended from the free end of the cable to keep the cable straight and at a certain length. If the temperature of the cable is reduced by 10 C degree, by how much should the suspended mass be increased so that the length of the cable remains the same? The coefficient of linear expansion for aluminum is alpha = 23 times 10^-6...

Question 8 please-show all work
You are building a mobile. It is connected to the ceiling by a rope. The hanging weights are attached to a massless beam. Use L = 0.25 m, D = 0.5 m, M_1, = 1 kg and M_2 = 1.5 kg. You have a third mass M_3 = 2 kg. Determine the tension in the rope connecting the beam to the ceiling and the location where you attached M_3 if you correctly placed it so...

Consider a cylindrical cable with a hanging weight suspended from it. When the mass is removed, the length of the cable is found to be l0 = 4.53 m. After the mass is added, the length is remeasured and found to be l1 = 5.46 m. Determine Young's Modulus Y in N/m2 for the steel cable if the weight has a mass m = 85 kg and the cable has a radius r = 0.045 m. If we were to...
