- You have hung a 0.500 kg mass from the end of a 1.00 m long pendulum and suspended it from the end of a force sensor so that it is at equilibrium. You tare the force sensor. You then set the pendulum in motion. At the bottom of the motion, the sensor reads -1.96 N. How much tension is there in the string, in N?A pulley-and-cable assembly supports a block W and it requires a force at P for equilibrium. Since block W has a mass of 30kg (g=9.806), calculate the force of the spring CD and the magnitude of force P.7. An Undamped spring mass system is used at a high efficient mixer. The Srping in the system as a spring consant of 30 pounds per foot. A container which weighs 10 pounds is placed on the spring. Thes sping mass system has a safety shut off when the mass moves beyond 1 ft. We want to acchieve a maximum amount of mixing with a external force which does not exceed 1 pound. a. What external driving force should we apply? b. At what time will the system trigger the automatic shut off? (Hint: zoom in on a plot)
