Acombination lock has a 1.3-cm-diameter knob that is part of the dial you turn to unlock the lock. to turn that knob, you twist your wrist as you grip it between your thumb and forefinger with a force of 5.0 n . suppose the coefficient of static friction between the knob and your fingers is 0.65.
what is the most torque that you can exert on the knob without having it slip between your fingers?

A55-kg pilot flies a jet trainer in a half vertical loop of 1200-m radius so that the speed of the trainer decreases at a constant rate. knowing that the plane has a speed of 550 km/h at point a, and the pilot experiences weightlessness at point c (i. e., the normal force from the seat bottom is zero), determine (a) the deceleration of the plane, (b) the force exerted on her by the seat of the trainer when the trainer is at point b.
