The machinist has a new task. He needs a new tapered cylindrical shank. The shank still needs to have a 0.75 taper per foot. The small diameter is 11 inches and the length is 17 inches. What is the large diameter?

Formula for the large diameter =

D = TL/ 12 + d

Where

T = Taper per foot in inches/foot

L = Length in inches

d = small diameter in inches.

The large diameter = 12.0625 inches

Step-by-step explanation:

Looking at the above question, we are told that a machinist is needs a Taper cylindrical shank.

Taper in machinery can be defined as what is used to attach the bit of a tool to the spindle of a machine. Taper when used in machinery operates using the principle of friction.

To calculate the Taper in a machinery, we use the formula:

T = (D - d)/ L × 12

T = Taper in inches/foot

D = Large diameter in inches

d = small diameter in inches

L = Length of the Taper in inches

From the above question, we are asked to find the Large diameter of the cylindrical tapered shank.

The formula for the large diameter can be derived from the Formula for a Taper

Since,

T = (D - d)/ L × 12

We would divide both sides by 12

= T/12 = (D - d) /L

Cross Multiply

= (T × L)/ 12 = D - d

D = (T × L)/ 12 + d

Hence, the formula for the large diameter =

D = TL/ 12 + d

Where

T = Taper per foot in inches/foot

L = Length in inches

d = small diameter in inches.

In the question, we are given:

Taper per foot = 0.75inches per foot

The small diameter = 11 inches

The length = 17 inches.

Hence,

Large diameter (D) = (0.75 × 17)/ 12 + 11

The large diameter = 12.0625 inches

idk the answer but just put a

4th option is correct xy=-10

if this was to u plzz mark me the brainliest
