A twist of 4 N•m is applied to the handle of the screwdriver. What is the force F required at the handle to generate this couple moment? What is the force P exerted on each end of the blade? Solution Twist = F*d 4 N.m = F * 0.03 F = 133.33 N Also P*0.005 = 4 P = 800 N Force P generated at the end of Blade is 800 N.
