An automatic washing machine has a mass of 65 kg. In order to avoid excessive vibration, the washing machine is kept on three springs. The stiffness of each spring is s. The washing machine motor rotates at 560 RPM. Determine the value of stiffness s of each spring for the condition that 10% of vibrational (Shaking) force is allowed to be transmitted to the supporting base.

4- A helical spring, when fixed at one end and loaded at the other, requires a force of 100 N to produce an elongation of 10 mm. The ends of the spring are now rigidly fixed, one end vertically above the other, and a mass of 10 kg is attached at the middle point of its length. Determine the time taken to complete one vibration cycle when the mass is set vibrating in the vertical direction. MF 10 AS HB 30 EA AA MA MOHAMMD SUTAN M

Mr. Ahmed is having Nissan patrol 4-wheel drive car. He used to take off road drive to reach his house. So frequently he observes vibration in his car while driving it at particular speed. He took his car to a workshop. The service personal has recommended for static balancing of the wheels of the car in order to cancel the vibration. Identify the condition from the following that must be satisfied to achieve static balancing. a. The net static force acting on the shaft is equal to zero. b. The net couple due to static forces acting on the shaft is equal to zero. c. Both (a) and (b). d. None of the given answers.
