O Degree Radians ? 50% Part (1) Determine the magnitude of the force exerted on the pivot point by the see-saw while in use in newtons. All cortml C 201S Espert TA·LLCExplanation / Answer
a] balancing torque, m1r1 = m2r2
62*(1.4 - 0.12-d) = 29*(1.4- 0.12 + d) + 9*d
d = 0.422 m
b] Force = mg = (62+29+9)*9.8 = 980 N
