1. MC · Levers

A balanced lever has a 40-pound load 2 feet from the pivot. How much downward force is needed on the opposite side, 4 feet from the pivot? Ignore the lever’s weight.

2. MC · Gears

Two external gears mesh directly. If the first gear turns clockwise, which way does the second turn?

3. MC · Pulleys

An ideal movable pulley supports a 100-pound load on two vertical rope segments. What pull is required to hold the load steady? Ignore friction and pulley weight.

4. MC · Pressure

The same downward force is applied to two flat supports. Support A has half the contact area of support B. How does A’s pressure compare with B’s?

5. MC · Work

A steady 30-newton force moves an object 4 meters in the direction of the force. How much work does that force do?

6. MC · Ramps

Two ideal ramps raise the same load to the same height. Ramp A is twice as long as ramp B. Ignoring friction, how does the steady force needed along A compare with B?

01

Mechanical Comprehension is pattern recognition

You do not need to be a mechanic to begin. Build from core ideas such as force direction, simple machines, pressure, motion, and energy transfer.

02

What you get

FORCE

Forces and motion

Practice how pushes, pulls, torque, friction, and gravity affect mechanical systems.

MACH

Simple machines

Master levers, pulleys, gears, wheels, axles, wedges, screws, and inclined planes.

FLUID

Pressure and fluids

Learn the basics behind hydraulics, pneumatics, buoyancy, and pressure changes.

VISUAL

Diagram reasoning

Train yourself to trace motion, compare loads, and identify the mechanical advantage.

03

What to practice

Levers and torque

Fulcrums, arms, load, effort

Pulleys and gears

Direction, speed, force tradeoffs

Hydraulics and pressure

Force through liquids and gases

Work and energy

Force over distance and mechanical advantage

04

Sample practice questions

Lever sample

A lever has the load closer to the fulcrum than the effort. What advantage does this create?

Answer: Less effort is needed to move the load
A longer effort arm increases mechanical advantage.
Gear sample

If a small gear turns a larger gear, what usually happens to the larger gear?

Answer: It turns more slowly with greater torque
Larger driven gears trade speed for turning force.
05

How to use this page

1

Learn the core machines

Start with levers, pulleys, gears, wheels and axles, inclined planes, wedges, and screws.

2

Draw force direction

When a diagram is confusing, trace where force enters and where motion leaves.

3

Drill by concept

Do focused sets by topic instead of mixing everything too early.

FAQ
