Question

2. For this series of 4 questions, a man sits in the chair which is pin-connected to the 10-m frame BC. Frame BC rotates counterclockwise. Your final goal is to determine the magnitude of the support force N exerted by the chair on the man at the instant 0 = 30°. But before that, you need to answer some other questions. Please pay attention: the numbers may change from problem to problem since they are randomized. 3) If the two unknowns, Nt and Nn, represents the tangential component and normal component of the support force N respectively, and the man has mass of m, select the correct equations of motion that, when used together, can solve for the support force Nexerted by the chair on the man at the instant 0 = 30°. Take g = 9.81 m/s2. А B 10 m e C
