WTMA exam key facts

The Wiesen Test of Mechanical Aptitude (WTMA) is a 60-item multiple-choice test of mechanical aptitude. Source
The Wiesen Test of Mechanical Aptitude takes 30 minutes to administer, and PAR requires a stopwatch for timing. Source
The Wiesen Test of Mechanical Aptitude has no fixed passing score; each candidate gets a raw score out of 60 and a percentile rank against the norm group. Source
PAR sells the WTMA Introductory Kit (item 4257-KT) for $464.00; employers buy it, and candidates do not pay a registration fee. Source

✍️ Sample WTMA Questions & Answers

1. Two identical balls are dropped from different heights. Ball A is dropped from 10 feet; Ball B from 20 feet. Compare their speeds just before hitting the ground.

✓ Ball B is about 1.4 times faster than Ball A

Speed is proportional to the square root of height (v = √(2gh)), so doubling height increases speed by √2 ≈ 1.4 times.

2. In a simple electrical circuit, if the voltage is doubled and the resistance remains constant, what happens to the current?

✓ It doubles.

According to Ohm's Law (V=IR, or I=V/R), current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R). If the voltage is doubled while resistance stays the same, the current must also double to maintain the relationship.

3. A bicycle rider coasts down a hill and gains speed. Which energy conversion is occurring?

✓ Gravitational potential to kinetic

As the rider descends, gravitational potential energy converts into kinetic energy, increasing speed.

4. Which material is the BEST conductor of electricity?

✓ Copper

Copper has very low electrical resistance and is one of the best practical conductors used in wiring.

5. A motor lifts a 500 lb load 10 feet in 5 seconds. What is the power output?

✓ 1,000 ft-lb/s

Power = (Force × Distance) / Time = (500 × 10) / 5 = 1,000 ft-lb/s.

6. A 6-tooth sprocket drives a 24-tooth sprocket. The driven sprocket rotates at what fraction of the driver's speed?

✓ One-quarter the speed

Speed ratio for chain drives = driver teeth / driven teeth = 6/24 = 1/4, so the driven sprocket turns at one-quarter the driver's speed.

What Practice Test Geeks adds beyond an AI chat for WTMA

An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:

A timed, full-length WTMA mock exam — 60 questions in 30 minutes with a 80% pass mark, modeled on the official exam's question count and time limit, followed by a score report broken down by exam domain.
A fixed WTMA question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
A printable WTMA cheat sheet you can print or save as a PDF.
WTMA flashcards built from the same question bank.
Free WTMA practice tests with the correct answer shown after each question.
