FORM TURNING - Practice Mode

1) What is the term the distance moved by the tool along the work for each revolution?
Correct Answer: Feed
Explanation:

The diameter of a circle is the distance across the circle through its center. To find the area of a circle, you can use the formula: A = πr^2

Where A is the area of the circle and r is the radius of the circle. The radius of a circle is half of the diameter.

In the case of diameter of 50cm the radius would be: r = 50 cm / 2 = 25 cm

So you can use the formula above to find the area of the circle: A = π * 25^2 = π * 625 cm^2 A = about 1962.5 cm^2

So, the area of a circle with diameter 50 cm is about 1962.5 cm^2.

2) What are the possible surface that can be produced by form turning?
Correct Answer: To generating concave and convex profile
3) Which type of tool is suitable to produce form surface in mass production activities?
Correct Answer: Using carbide tipped form tool
4) What factor is important in free hand form turning?
Correct Answer: Skilled labour
5) Which type of jig is used to hold thin and soft parts?
Correct Answer: Sandwich jig
Explanation:

The circumference of a circle is given by the formula C = 2 * pi * r, where r is the radius of the circle, pi is a mathematical constant (approximately equal to 3.14) and C is the circumference.

In this case, the diameter of the circle is 7 cm. To find the radius, divide the diameter by 2: 7 cm / 2 = 3.5 cm

So, to find the circumference of a circle with a diameter of 7 cm, we can substitute this value for r in the formula: C = 2 * pi * 3.5 cm = 7 * pi approximately 22.0 cm

So the circumference of a circle whose diameter is 7 cm is approximately 22.0 cm.
