Question 1 The board is used to hold the end of a fourway lug wrench in position as shown in Fig. 1. Force F lies in a vertical plane. (a) If a force of F = 100 N is applied, determine the magnitude of the moment produced by this force about the x axis. (8 Marks) (b) If a torque of 30 N111 about the x axis is required to tighten the nut, determine the required magnitude of the force F that the man's foot must apply on the end of the wrench in order to turn it.
