Free Wiesen Test of Mechanical Aptitude (WTMA) Practice: 60 Questions, 30 Minutes

The Wiesen WTMA is the short, language-light mechanical reasoning test Criteria Corp and several direct employers use for technician and operator hiring. 60 items, 30 minutes, 30 seconds per question. The 6th-grade reading level makes the test fair to non-native English speakers, but the mechanical intuition required is the same as any harder exam.

What this free WTMA practice includes

The Wiesen tests mechanical reasoning exclusively. There is no math section, no reading section, no pattern recognition. Every item shows a diagram of a mechanical situation and asks a single prediction: which side requires more force, which way the gear turns, which container cools fastest. The test is short, fast, and surprisingly unforgiving if your mechanical intuition is weak.

This simulation uses 60 items drawn from the standard Wiesen concept families (basic machines, pulleys, gears, gravity, electricity, heat and fluids, everyday physics) under a strict 30-minute clock. Your raw score maps to a simulated percentile against a general-population norm.

Three WTMA sample questions with walkthroughs

Three items from three different Wiesen concept families.

Sample 1: Basic Machines (Levers)
A crowbar is used to pry open a crate. You grip the crowbar 40 cm from the pivot and push down. The crate lid is 10 cm from the pivot on the other side. If you push down with 20 kg of force, approximately how much force is applied to the crate lid?
  • A.20 kg
  • B.40 kg
  • C.60 kg
  • D.80 kg
  • E.100 kg
Answer and walkthrough
D. Lever balance: force times distance equals force times distance. 20 kg times 40 cm equals 800. 800 divided by 10 cm equals 80 kg. The crowbar multiplies your 20 kg input to 80 kg of prying force because your grip is 4 times farther from the pivot than the load.
Sample 2: Gears
Two gears are meshed. The driving gear has 30 teeth and spins at 60 RPM clockwise. The driven gear has 15 teeth. At what speed and direction does the driven gear spin?
  • A.30 RPM clockwise
  • B.30 RPM counterclockwise
  • C.60 RPM counterclockwise
  • D.120 RPM clockwise
  • E.120 RPM counterclockwise
Answer and walkthrough
E. Speed: tooth ratio is inverse, so 30 over 15 equals 2. The driven gear spins at 2 times 60 equals 120 RPM. Direction: meshed gears reverse, so clockwise driver produces counterclockwise driven. Answer: 120 RPM counterclockwise.
Sample 3: Everyday Physics (Heat Transfer)
You touch a metal doorknob and a wooden door in a room that has been cold overnight. Both are at the same temperature, but the metal feels colder than the wood. Why?
  • A.The metal is actually at a lower temperature
  • B.Metal conducts heat away from your hand faster than wood
  • C.Wood is warmer than metal at all temperatures
  • D.Your hand is colder than the metal
  • E.Wood absorbs moisture that warms it
Answer and walkthrough
B. Metal is a much better thermal conductor than wood. When you touch metal, heat flows from your warmer hand into the metal rapidly, which your nerves register as cold. Wood conducts heat slowly, so less heat leaves your hand, and it feels less cold. The two materials are at the same temperature; the difference is conductivity.

What the real Wiesen WTMA feels like

The real Wiesen is usually administered online through Criteria Corp's platform or a direct employer portal. You log in, the 30-minute clock starts, and you work through 60 items as fast as you can. Each item has a diagram or a short text scenario and 3 or 4 answer choices. There is a next button, a clock, and minimal chrome on the interface.

The test does not allow backtracking in most implementations. You answer an item and move forward. This is why pacing discipline matters: you cannot return to question 12 once you are on question 30.

Employers who use the WTMA tend to be in manufacturing, utilities, logistics, and transit. Entry-level operator roles cut at the 50th percentile. Technician roles cut at the 70th. Few roles cut higher because the test is designed as a screen, not a ranking tool.
