Question

Finding the weight of the hanging mass Find the weight of the hanging mass when the spring, with spring constant 15. 0 kN/m has been stretched 12. 5 cm. The tension in rod BD is 3330 N. Recall that the pulley is massless. Determining the displacement of a spring The cable segment attached to the spring is at an angle of Phi = 40. 0 degree from the ground. The spring has a spring constant of k = 15. 0 kN/m. The pulley is attached to the ceiling by rod BD that forms an angle theta = 65. 0 degree with the ceiling. The hanging mass causes a tension of 3400 N in rod BD. What is the displacement of the spring?

Explanation / Answer

T = kx = 0.125 *15*10^3 = 1875 N
