Assessment Objectives

General Skills

• Draw a force diagram of the forces on an object.
• Fill out a force table .
• Use a force table to solve an equilibrium problem .
• Recognize the importance of a basis.
• Find the components of a force acting at an angle. (See Component Form in the Vectors appendix.) You can practice this here .
• Solve an equilibrium problem involving a block on a ramp, with a tilted axis.

Specific Force Types

• Recognize that the static frictional force is normally an adjustable force. (cf Static Friction)
• Solve Slipping Problems, using the static friction breaking point to find the extreme value of some other quantity.
• Given the mass of an object, calculate its weight, and vice versa.

Torque

• Calculate the torque on an object due to a force, where the torque is perpendicular to the lever-arm.
• Calculate the torque when it is not perpendicular to the lever-arm.
• Solve an equilibrium problem involving torques.
