a) Determine the stiffness constant of a vertical spring if it stretches by 1.4 cm when an object of mass 3.2 kg is hung from the free end of the spring. (b) For the same spring in Part (a), how far will the spring stretch if the 3.2 kg object is replaced by an object of mass 2.5 kg? (c) For the same spring in Part (a), determine how much mass is hung on the free end of the spring...
The spring has a stiffness of k=800N/m and an unstreches length of 200mm. Determine the force in cables BC and BD when the spring is held in the position shown.
Show step by step. If a 0.4 kg object hanging from a spring stretches it by 0.75 m, then by how much will the spring be stretched (in m) if a 0.8 kg object is suspended from it?
The torsional spring at A has a stiffness = 25 N.m/rad and is undeformed when the uniform 20-kg bars OA and AB are in the vertical position and overlap. If the system is released from rest with 0 = 67°, determine the magnitude of the angular velocity of wheel B when 0 = 25º. The 13-kg wheel at B has a centroidal radius of gyration of 50 mm and is observed to roll without slipping on the horizontal surface. kr...
