force F of 30 N is applied to a door. Find the torque if F is applied to the door: a) 0.80 m from the hinge with F perpendicular to the door. b) 0.60 m from the hinge with an angle of 30° between the door and F. c) 0.30 m from the hinge parallel to the door

Question on attached image.  In the drawing to the right, a 90.0 cm long metal bar having a mass of 0.500 kg is supported by two strings as shown.  a) Determine the value of the tension in each string.  b) Calculate the position of the center of mass from the left end of the torque bar.

Two forces are applied to a door. Both forces are applied at the door knob, and both forces have the same magnitude. The first force is applied perpendicular to the door, and the second force is applied at 15 degrees to the plane of the door. Which force exerts the greater torque about the door hinge?

A rectangular bar is hinged at point O.  The bar is 3.00 m long and 2.00 m wide.   Find the torque resulting from the following force about an axis through point O: F1 = 1 N. Use a positive for a counterclockwise torque and a negative for a clockwise torque.

A uniform 8.00 m, 1500 kg beat is hinged to a wall and supported by a thin cable attached 2.00 m from the free end of the beam. The beam is fixed to the wall by a hinge at an angle of 30.0 degrees above the horizontal. The angle between the cable and the beam is 40 degrees. What is the direction of the torque exerted by the beam around the point where the cable is attached? -clockwise -counterclockwise

A 420-N uniform rectangular sign 4.00 m wide and 3.00 m high is suspended from a horizontal, 6.00-m-long, uniform, 130-N rod as indicated in the figure below. The left end of the rod is supported by a hinge and the right end is supported by a thin cable making a 30.0° angle with the vertical. (Assume the cable is connected to the very end of the 6.00-m-long rod, and that there are 2.00 m separating the wall from the sign.) 30.0 IE CEAM MOP (a) Find the (magnitude of the) tension T in the cable.
