Question

The figure below is a long stick with evenly spaced marks. The distance between two adjacent marks is 15.60 cm. For each of the following forces or set of forces determine the requested torque. Use Point K as the axis of rotation. Use the sign convention that a counterclockwise (CCW) torque is considered positive and a clockwise (CW) torque is considered negative. A force of 11.0 N is directed upward perpendicular to the stick at Point D. What is the torque from this force? Submit Answer Incorrect. Tries 2/10 Previous Tries A force of 24.0 N is directed downward perpendicular to the stick at Point L. What is the torque from this force? ON m Submit Answer Incorrect. Tries 1/10 Previous Tries A force of 14.0 N is directed upward perpendicular to the stick at Point F. What is the torque from this force? Submit Answer Incorrect. Tries 1/10 Previous Tries A force of 25.0 N is directed upward at angle 34.9° to the right of the perpendicular to the stick at Point D. What is the torque from this force? Submit Answer Tries 0/10 A force of 24.0 N is applied horizontally to the right at D. What is the torque from this force? Submit Answer Tries 0/10 Two forces are applied simultaneously to the stick. A force of 11.0 N is directed upward perpendicular to the stick at Point D and a force of 14.0 N is directed upward perpendicular to the stick at Point F. What is the net torque from these two forces? Submit Answer Tries 0/10

Explanation / Answer

a) T = r*f = 3*0.156*11 = 5.148 Nm

b) T = -6*0.156*24 = -22.464 Nm

c) T = -2*0.156*14 = -4.368 Nm

d) T = 3*0.156*25*sin34.9 = 6.694 Nm

e) T = 0 because angle is zero

f) T = 5.148-4.368 = 0.78 Nm
