The mechаnism belоw cоnsists оf а weightless collаr sliding without friction on vertical bar EF. A frictionless, weightless pulley is attached to the collar at pin G. The cable ABCD is attached to the pulley. The end of the cable at A is fixed while the other end at D is being pulled on with force T. There is also a spring attached to the collar at an angle 60° from horizontal. The spring has a stiffness of 20 lb/inch and has a deflection (L – L0) of 1 inch. a.) Draw a free body diagram of pin G. b.) What is the magnitude of the spring force exerted on the collar (lb).
