Question

W1210 D=0.750 H 22. A 60 degree slot has been machined in a fixture. The slot is checked by placing a pin in the slot and indicating the distance between the top of the fixture and the top of the pin as shown in the accompanying figure. Compute distance H to three decimal places by using the formula: H= 1.5x D-0.866 x W. All dimensions are in inches. a. 0.069 in b. 0.077 in c. 0.083 in d. 0.090 in A=3 in. B-2.5 ft FIGURE 18-5 23. Length A in the accompanying figure is 3 inches and length B is 2.5 feet. Determine the ratio of length A to length B in lowest fractional form. 1/15 b. 1/10 c. 1/5 d. 1/2 a. I

Answer 1

Q.22. Ans

From figure we have, D = 0.75 and w = 1.210

We are provided with a formula of distance, H in problem itself.

Therefore by using the formula,

H = 1.5 x D - 0.866 x W

H = 1.5 x 0.75 - 0.866 x 1.210 = 0.07714 in

Therefore, option (b. 0.077 in) is the correct answer.

Q23.Ans

From figure we have,

A = 3 in, &

B = 2.5 ft = 2.5 x 12 in = 30 in

We know that 1 ft = 12 in

Therefore, ratio of A to B in the lowest fractional form is given by

A / B = 3 / 30 = 1/10

Therefore, option (b. 1/10) is the correct answer.
