Sample Practice Test Questions
If AD = 29 and BD = 22, AB = ?
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BDWhich of the following is a relay that connects the battery to the starter motor when the ignition key is turned?
solenoid
The cylindrical solenoid is a relay that safely connects the high amperage battery to the starter motor when the ignition key is turned. This current then allows the engine to turn at a high enough speed to start.
"For every action, there is an equal and opposite reaction." This describes which of Newton's laws of motion?
third
Newton's third law of motion states that For every action, there is an equal and opposite reaction. When an object exerts a force on another object, the second object exerts a force of equal magnitude in the opposite direction on the first object.
A constant velocity (CV) joint is closely related to which of the following?
universal joint
Like CV joints, universal joints (U-joints) are located at each end of a drive shaft and allow the shaft to operate at a variable angle with the item it is driving. Universal joints perform the same basic function as CV joints but CV joints have a wider range of operation.
Specific gravity is a comparison of the density of an object with the density of:
water
Specific gravity is the ratio of the density of equal volumes of a substance and water and is measured by a hyrdometer.
Simplify \( \sqrt{8} \)
To simplify a radical, factor out the perfect squares:
