The quarter circular rod lies in the horizontal plane and supports a vertical force P at its end. Suppose that 00 90 (Figure 1) Figure <1 of 1 A 90 Determine the magnitude of the torque acting in the rod as a function of the angle Express your answer in terms of some or all of the variables P, r, and 0. View Available Hint(s) 4 Hint 1. How to determine T First, establish the x, y, z coordinate axes in any suitable orientation. The torque occurs about the rod's axis for any angle. So, you need to consider the moment equilibrium about this axis to find T as a function of 0. vec T= Pr cos 0 F -> ? Submit Previous Answers Request Answer x Incorrect; Try Again; 4 attempts remaining Perhaps you do not distinguish between the moment and the torque acting on the rod. Note that M and T occur about two mutually perpendicular axes. You may want to review Hint 1. How to determine T
