Question

Please help with the solution to this problem:

4. Determine the amount of torque applied by each force: e. 15 N, 25° a. A 10.0 N force applied tangenlyto a wheel with a diameter of 0.500 m. c.15 N b. A 20.0 N force applied tangentially to the middle of a 2.50 m stick f. 15 N, 25 c-g. A 6.0 m piece of wood is free to rotate through a pin in the center. Force are applied at different places. The angles listed is the acute angle made from the head of the vector and the piece of wood. The force in the middle are exactly halfway between. For each force, calculate the torque that develops, the direction of torque, and the direction of rotation h. 15 N, 60 g. 15 N, 30 d. 15 N

Explanation / Answer

4. torque =r x F = r F sin(theta)

(A) torque = (0.500/2)(10)(sin90)

= 2.5 N m

(B) theta =0 and sin0 = 0

torque = 0

(C) torque = - (1.5 x 15)+(3 x 15) + (3 x 15 sin25) + (1.5 x 15 sin25) - (1.5 x 15 sin30) + (1.5 x 15 x sin60)

torque = 59.3 N m

direction of rotation = counter clockwise
