rope wrapped around a pulley of radius r is pulled with a force F, as seen in the figure. The magnitude of the torque due to F about the pivot point is determined by |τ|=|rxF|=rFsinθ. Choose the value that correctly identifies the angle θ that results in a correct calculation of torque. a) 90 degrees b) 180 degrees c) 0 degrees d) Not enough information

A machinist is using a wrench to loosen a nut. The wrench is 25.0 cm long, and he exerts a 17.0 N force at the end of the handle at 37∘ with the handle. What torque does the machinist exert about the center of the nut? Express your answer with the appropriate units. Enter positive value if the rotation is counterclockwise and negative value if the rotation is clockwise.

Which one of the forces in the figure produces the largest magnitude torque about the rotation axis indicated? (All forces have the same magnitude, the shape is triangle with all sides equal) Axis F2 O a. F4 O b. F3 The same torque is exerted by each force О с. O d. F2 O e. F1

A wrench is used to apply a torque to a bolt. Forces F1 through F6 all have the same magnitude. The point of application of force F1 (and F4) is a distance d from the center of rotation of the bolt. The application points of F1, F2, and F3 are all distance d apart, as shown. Use the convention that counter-clockwise torques are positive; clockwise torques are negative. 1)Determine the torque applied on the bolt by F2 in terms of the variables and angles given in the problem.  2)Determine the torque applied on the bolt by F3 in terms of the variables and angles given in the problem.  3)Determine the torque applied on the bolt by F4 in terms of the variables and angles given in the problem.
