Here is just a glimpse into the type of questions we offer in our practice pack, which includes four online practice mechanical comprehension tests. JobTestPrep's online practice pack allows you to practice complete tests, each containing more than 20 questions, including a smart score report and thorough explanations.
Sample question 1On which pole does the weight press harder?
- The weight equally presses both poles
Solution: The pressure on the pole is influenced by two factors - the weight and the distance between the resting point and the pressure point. On the pole in Figure 2 there will be more pressure as it is farther away from the resting point.
Therefore, the correct answer is 2.
Sample question 2What would be the current flowing through point X if another identical power source were to be added in parallel to the circuit?
1. Twice as strong
2. Half as strong
3. There is no difference
Solution: Adding a power source in parallel does not change the values already set for the circuit, as they match the existing power source. Adding a cell or battery in parallel is usually devised as a form of electrical backup to a circuit, and not as a means to change the voltage.
Therefore, the correct answer is 3.
