The figure shows a bicycle wheel resting against a small step whose height is h = 0.100 m. The weight and radius of the wheel are W = 20.0 N and r = 0.390 m. A horizontal force is applied to the axle of the wheel. As the magnitude of increases, there comes a time when the wheel just begins to rise up and loses contact with the ground. What is the magnitude of the force when this happens? Number Units ✪ F

a. What is the moment caused by the force, F =223 lbf, on the wrench with length, L=8 in, around the bolt as shown if 0=35°? Report your answer in ft-lbs with the direction of the moment.* F 0 L b. What is the moment caused by the force, F = 221 lbf, on the wrench with length, L=19 in, around the bolt as shown if 0 =143° and a = 52° ? F 0 7- α

Review Determine the moment of force F about the y axis. Determine the moment of force F about the , the y, and the z axes. Assume F = 570 N. (Figure 1) Express your answer to three significant figures and include the appropriate units. My = -137 N-m Submit Previous Answers v Correct Correct answer is shown. Your answer -136.8 N-m was either rounded differently or used a different number of significant figures than required for this part.
