- A bar 2.0 ft. long is pivoted at its center. A 4.0-lb weight is hung from one end and a 1.0-lb weight from the other end. At what distance from pivot (fulcrum) must a 25-lb weight be placed to balance the bar? Make a drawing that illustrates this torque problem.A bolt is turned by a force of 51 N which is applied perpendicularly at the end of the handle of a wrench. The wrench is 0.31 m long. What is the torque applied by the wrench?A 20-cm-long wrench is used to tighten a nut. The wrench handle is pulled at 35° from the perpendicular of the handle with a force of 60 N. How much torque is exerted on the nut?
- A turn table starts from rest and reaches 11 rad/s of angular velocity in 9.5 s. Find the angular acceleration in rad/s/s. Answer:I need help with this physics torque questionA force is applied to pull a wheel over a step. Determine the minimum force necessary if h = 3.0 cm, r = 6.0 cm and the wheel has a mass of 1.4 kg. Use g = 10 N/kg. Hint: Take torques about the corner of the step. It is easier to use the perpendicular form of the torque formula because most of the given lever arm information is given perpendicular to the axis of rotation. To determine the lever arm of the weight of the wheel I set up a 30,60,90 triangle base on h and the radius.
