A force of 100 N is applied to a wheel, as shown in the illustration below. The radius of the wheel is 20 cm, and the radius of the axle is 5 cm. For the wheel to rotate at constant speed, determine the torque and direction of the friction force applied to the axle. 1.25 N·m, clockwise F 1.25 N·m, counter-clockwise 20 Nm, clockwise 20 N·m, counter-clockwise
A screwdriver that is 12 cm long is used to pry open the lid of a paint can. The person doing this applies a downward force of 100 N at the handle end of the screwdriver and supports the screwdriver on the edge of the can 1 cm from the screwdriver's tip. What is the force required to lift open the paint can without the screwdriver? 120 N 1200 N 2000 N 12000 N
In the illustration below, a fulcrum is placed at a point 2/5 the length of a 200-g rod from its left end, a 6-kg mass is attached to the left end of the rod, and a 2-kg mass is attached to the right end. To produce rotational equilibrium, where should a 3rd mass (1-kg) should be attached... to the left end of the fulcrum to the right side of the fulcrum nowhere, the mass is not large enough nowhere, the rod is already balanced
