✍️ Sample OAR Questions & Answers
1. A storage facility charges $1.25 per square foot per month. If a unit measures 10 feet by 14 feet, what is the total cost for 6 months?
✓ $1,050
The unit is 140 sq ft (10 × 14), costing $175/month (140 × $1.25), so 6 months costs $175 × 6 = $1,050.
2. A 5 kg block on a frictionless surface is pushed by two horizontal forces: 20 N east and 10 N west. What is the magnitude of the block's acceleration?
✓ 2 m/s²
Net force = 20 − 10 = 10 N east; a = F/m = 10/5 = 2 m/s².
3. Which of the following is a binomial?
✓ 3x + 5
A binomial has exactly two terms; 3x + 5 has two terms.
4. If voltage doubles while resistance stays constant, what happens to power?
✓ Power quadruples
Since P = V²/R, doubling voltage squares the effect, so power quadruples.
5. A wrench slips off a bolt head because the wrench opening is slightly too large. This is most likely to cause:
✓ The bolt head to round off (strip)
An oversized wrench rocks on the corners of the bolt head, shearing them off and rounding the head.
6. Which of the following best describes a force couple?
✓ Two equal and opposite forces that produce rotation
A couple consists of two equal, opposite, non-collinear forces that produce pure rotation (torque) with no net linear force.
