Sample Practice Test Questions
For inline cylinder arrangements in an engine, how are the cylinders numbered?
sequentially from the front of the engine to the back
Inline cylinder arrangements number cylinders sequentially (1, 2, 3, ...) front to rear.
A welding rod provides:
the joining material for a weld
The joining material for a weld is called a welding or filler rod and is available in a variety of diameters and alloys for different welding tasks.
A large naturally occurring community of flora and fauna occupying a major habitat is:
a biome
A biome is a large naturally occurring community of flora (plants) and fauna (animals) occupying a major habitat (home or environment).
The formula for the area of a circle is which of the following?
a = π r2
The circumference of a circle is the distance around its perimeter and equals π (approx. 3.14159) x diameter: c = π d. The area of a circle is π x (radius)2 : a = π r2.
a(b + c) = ab + ac defines which of the following?
distributive property for multiplication
The distributive property for multiplication helps in solving expressions like a(b + c). It specifies that the result of multiplying one number by the sum or difference of two numbers can be obtained by multiplying each number individually and then totaling the results: a(b + c) = ab + ac. For example, 4(10-5) = (4 x 10) - (4 x 5) = 40 - 20 = 20.
What type of load creates different stresses at different locations on a structure?
non-uniformly distributed load
A concentrated load acts on a relatively small area of a structure, a static uniformly distributed load doesn't create specific stress points or vary with time, a dynamic load varies with time or affects a structure that experiences a high degree of movement, an impact load is sudden and for a relatively short duration and a non-uniformly distributed load creates different stresses at different locations on a structure.
Connected gears of different numbers of teeth are used together to change which of the following charasteristics of the input force?
torque
Connected gears of different numbers of teeth are used together to change the rotational speed and torque of the input force. If the smaller gear drives the larger gear, the speed of rotation will be reduced and the torque will increase. If the larger gear drives the smaller gear, the speed of rotation will increase and the torque will be reduced.
Collinear forces:
act along the same line of action
Collinear forces act along the same line of action, concurrent forces pass through a common point and coplanar forces act in a common plane.
