FE / Engineering Mechanics
Practice drills
Open a unit-specific drill page and work through it step by step. Each page is built so you can attempt first, then reveal the next step only when you need it.
All Engineering Mechanics drills are temporarily open through June 30, 2026.
Unit 1
Force Systems
Resultants, centroids, and moment of inertia. This is the most stable math-first scorer in the subject.
Drill focus
- - Simply supported beam reactions
- - Composite centroid with negative areas
Unit 2
Equilibrium
Beam reactions, free-body diagrams, and classic contact problems. This is the safest high-ROI unit.
Drill focus
- - UDL plus point load
- - UVL over full span
Unit 3
Friction and Trusses
A mixed unit: friction is direction-sensitive, while trusses are method-heavy and repetitive.
Drill focus
- - Ladder friction minimum angle
- - Ladder friction with a person climbing
Unit 4
Kinematics
The motion-description unit. Projectile and rectilinear problems are the safest scorers; variable acceleration is the trap.
Drill focus
- - Rectilinear motion: x = f(t)
- - Projectile: max height and range
Unit 5
Kinetics
Newton second law, work-energy, and impact. This unit scores well if you pick the right method family for the question.
Drill focus
- - Newton on an incline
- - Work-energy
All practice drills are free through June 30, 2026
The usual one-free-drill sampler rule is temporarily suspended. Every unit drill and worked diagram is open this semester.
