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.
