2. What is the function of a feeler gauge

3. Difference between a vice grip and a wrench in terms of their structure and function s.

4. Why do some mechanics use allen keys instead of self-tapping screws to fasten joints.

5. Explain the method by which a micrometre is used to determine the depth or size of an object.

6. Describe why engineers or technicians may prefer a vernier calliper to other measuring instruments

Answer 1

Part 1

A technique used by mechanical engineers or motor technicians to tighten engine nuts with a ratchet.

1) Understanding the various types of ratchets

2) Instructions for using a ratchet on an automobile

Step 1: Examine the bolt or nut to be removed.

Step 2: Determine the bolt's position.

Step 3: Determine the size of the bolt and choose the appropriate socket.

Step 4: Connect the socket to the ratchet or extension.

Step 5: Determine the ratchet's location and orientation.

Step 6: Attach the socket and ratchet to the bolt and turn the handle clockwise.

Part 2

A feeler gauge is a hand-held instrument used to measure the breadth of a gap between two close together items. They are highly popular with mechanical engineers because they need a very exact clearance description between two pieces where a calliper or tape measure would not fit.

Part 3

Vice grips are the additional pair of hands that every DIYer requires. The locking function enables them to be clamped firmly and remain so while making a cut, measuring, or releasing a stripped bolt. Common vice grips resemble a heavy-duty pair of pliers. A wrench is a tool used to give grip and mechanical advantage when applying torque to turn or prevent rotating objects (often rotational fasteners such as nuts and bolts). The term wrench is commonly used in North American English. The two most frequent forms are open-end wrenches and box-end wrenches.

Part 4

Torque force is centred on the driver's leading edge. A screw with four contact points is significantly less likely to strip the head than a slot head with two contact points. Allen drive is improved once again, with 6 points of contact. Allen and Robertson, among others, have the advantage of "locking in alignment" with the driver, making them far more user pleasant. Modern machinery is far more advanced and compact. That implies the engineers must employ every technique in their arsenal to achieve accessibility. Because Allen keys are so common, Torx drive lends credence to your issue.

Part 5

Depth micrometres feature a base that lines up with the top of the recess being measured. The thimble is attached to a shaft that protrudes from the base. A measuring rod descends from the shaft as the thimble spins. Continue to spin the rod until it reaches the bottom surface of the hole is measured.

Part 6

Both the Vernier calliper and the micrometre are frequently employed in the industry for everyday quality control. Both are simple to use and simple to measure. Both the Vernier Caliper and the Micrometer are accessible in digital form. That implies we can process more accurate and precise measurements.
