Chapter 67, Problem 7A

To determine

(a)

The find the height $\left(H\right)$ of gage block with use of sine bar.

Answer to Problem 7A

  $H=10"$.

Explanation of Solution

Given information:

Length of the gage block $\left(L\right)$ $=10”$ ; Sine bar angle $(\theta )$ $={35}^{\circ }$

Concept Used:

As it's known that A sine bar is generally used with slip gauge blocks. The sine bar forms the hypotenuse of a right triangle, while the slip gauge blocks from the opposite side.
