Question

the axis of rotation rotational speed &Her ui! 12 rad/s 3.6 (c) What is her initial and final KE? 010 Torque not at 90°. A small 42.0 N sign is suspended from the end of a hinged rod, which is 2.40 m long and uniform shape as shown in the diagram (a) What is the torque cause by the CG (center of mass) of the rod? Is it positive or negative? で -36 1.2 :1-48.2 Nm CG 360N 420N (b) What is the torque cause by the sign? ls it positive or negative? 12m+ 24m (c) What is the torque cause by the tension force, F, exists in the rope holding up both the rod and the sign? The rope makes an angle of 60° with the 36.0 N rod. the equilibrium condition, solve the equation to find out the magnitude of the tension force.

Answer 1

Part a and b are correct Part C) Torque due to Tension = + 2.4 times F sin 60 degree Z^vector_T = + 2.0784 F Nm Z^vector_net = 0 -43.2 - 100.8 + 2.0784 F = 0 2.0784 F = 144 F = 144/2.0784 F = 69.284 N Answer Tension in Rope
