Physics Torque Questions...?
Hey everyone! I need help with the following physics questions. Answering either one is greatly appreciated!
1) A mechanic exerts a 20-lb force at the end of a 10-inch wrench. If this pull makes an angle of 60 degrees with the handle, what is the torque produced on the nut?
2) A space station is constructed in the form of a rotating wheel 40 meters in radius. The acceleration produced at the wheel's rim is to be 2m/s^2. What must be the period of rotation (time for one complete revolution)?
1) Q = f*r*sinΘ = 20*10*sin60° = 173.2 in-lb
2) T = 2π√(R/a) = 28.1 sec
