d) Calculate resultants of co-planar force systems
e) Calculate moment of a force
f) List the Principle of Moments
g) Calculate resultant moment from couples - Equilibrium of Force Systems
a) Draw Free-Body Diagram and identify conditions of equilibrium
b) Describe equilibrium of concurrent, parallel, and non-concurrent force systems
c) Calculate unknown forces for an equilibrium system - Truss and Frame Analysis
a) Use method of joints and sections to calculate internal force in trusses
b) Diagram frames and calculate internal and external reactions in frames - Friction
a) Identify friction and normal force
b) Differentiate cases of actual from maximum static friction
c) Identify frictions for different surface of contact
d) Calculate friction for block with oblique surfaces and wedges
e) Define friction with belts and perform primary friction calculation - Centroids and Centers of Gravity
