Actual Qs and Ans - Expert-Verified Explanation -Guaranteed passing score -68 Questions and Answers

-Format: Multiple-choice / Flashcard

Question 1: Circular Saw

Answer:

Usually has a 7-1/4 inch-diameter blade, is much faster for cutting wood, especially for rip sawing, and for sawing plywood or other panels

Question 2: Corrosion-preventing chemicals

Answer:

can avoid problems blamed on "dead batteries", these chemical often show up as red spray on the terminal

Question 3: Sheaves

Answer:

MA = Driven diameter/Drive diameter

Question 4: Inclined Plane

Answer:

MA = horizontal length/vertical rise NOTE** to find the mechanical advantage, measure horizontally and vertically (Don't measure diagonally across the ramp)

Question 5: class 3 lever

Answer:

Another example of a lever is the human forearm: the fulcrum is the elbow, the effort is applied by the biceps muscle, and the load is in the hand.

Question 6: Shock Absorbers

Answer:

NOTE: When this wears out, a car tends to wander on the road because the springs aren't limited by the this.

Question 7: Bearings

Answer:

ball bearings and roller bearings.Cars have these wherever rotating parts are found: steering wheel, engine, transmission, drive shaft, differential, and axles.

Question 8: Fuel System

Answer:

fuel tank, the fuel filter, and the carburetor or fuel injector.

Question 9: Ohm's Law

Answer:

Describes the relationship between voltage, amperage, and ohms:

A = V/ ?

Question 10: Class 2 Lever

Answer:

levers have the load between the effort and the fulcrum. A wheelbarrow is

• The wheel's axle is the fulcrum, the handles take the effort, and the load is placed between them.

The effort always travels a greater distance and is less than the load.

Question 11: Gears

Answer:

Number of teeth on Driven gear/ Number of teeth on the Driving gear = MA

Question 12: Micrometer

Answer:

Very similar in purpose to the Vernier Caliper however more precise in measurement

Question 13: Compound Machine

Answer:

To find the MA of a this, multiply the MA of the simple machines together.

Question 14: Voltage

Answer:

Annotated as a capital V, force that affects the rate at which electricity flows through a conductor (aka: electrical pressure). The higher it is the more likely electricity will "leak" across an insulator or an air gap.Question 15: The differential has three jobs:

Answer:

• Allow different movement of the two axels, so that the car can turn a corner.
• Change drive directions. In rear-wheel-drive cars, it connects to the drive shaft that runs from front to

back and powers the axles, which run from side to side.

• Increase Power. It usually reduces the drive speed, so that three to four input revolutions create one

turn of the axles.

Question 16: Disk Brakes

Answer:

are an immense improvement over drum brakes because they offer shorter stopping distances and better control.

Question 17: Water Pressure

Answer:

Note: in a container also exerts pressure on the bottom of the container, the deeper the water, the greater the pressure. To find the amount of this in a tank, calculate the total weight of the water and divide by the area of the tank.

Question 18: pipe cutter

Answer:

used for copper, not steel

Question 19: Tin Snips

Answer:

designed to cut curves.

Question 20: carpenter's square

Answer:

is a guide for establishing right angles (ninety-degree angles), usually made of metal and in the shape of a right triangle.

Question 21: Amperes

Answer:

Annotated as a capital A, represents current strength

Question 22: Friction

Answer:

acts as a resistance to the movement of an object

Question 23: General Information( welding, Soldering, and Brazing)

Answer:

Welding, soldering, and brazing are fastening methods that use molten metal. Welding melts the metal that is being fastened. Soldering and brazing metal a separate metal, called solder or brazing rod, to make the attachment. Soldering is used for plumbing, for electrical or electronic equipment. To solder, clean the parts, apply flux, heat, and then touch the solder to the heated parts.Brazing is similar to soldering with the exception that the joining material is bronze.

Question 24: Wood Chisel

Answer:

cut wood when they are struck with a hammer or mallet.

Question 25: Forces

Answer:

pushes or pulls between objects
