Question
KMP11-Spring 2018 Item 7 7 of 12> Constants | Periodic Table Part A Certain critical bolts on a bicycle (like the ones that attach the handlebars) must not be over (or under) tightened. You might see a 'max torque' value etched in the metal next to the bolt. I wish to apply the maximum recommended torque of 15.5 N·m to the bolts holding the handle bars in place. To achieve this torque, with what force must I pull on the end of a 25.0 cm -long wrench if I pull (a) at right angles to the wrench shaft and (b) at 107 °to the wrench shaft? Submit Request Answer Part B Fo - Submit Request Answer Provide Feedback Next >Explanation / Answer
a)
Torque is given by
T=RFSin(o)
=>15.5 =0.25*F*sin90
F=62 N
b)
=>15.5 =0.25*F*Sin107
F=64.83 N
