What amount of force would be required to cause the same torque as in problem 1 if the force is exerted in the same place, but at an angle of 53° from the wrench? Answer: The formula for torque is: Ï = r x F = rFsinθ So for an angle of 60 0: Ï = (0.84 m)(45 N) sin (60 0) = 32.7 Nm = 33 Nm If the force is applied at an angle of 90 0 to the radius, the sin factor θ becomes 1, then the torque value is: Ï = rF = (0.84 m)(45 N) = 37.8 Nm = 38 Nm Problem #2 A= 40; B=10 _____ If A turns one time, B will turn _____. simple harmonic motion problem answers pdf.
