Required information Sally is making a sine bar, which is used to machine angles on parts (see the given figure). She has a 1.250-inch-thick bar that needs 90° grooves machined into it for precision ground 1.0000-inch diameter cylinders. A sine bar is used by placing different thicknesses under one of the cylinders so that the proper angle is attained. Sally wants the distance between the centers of the cylinders to be D= 5.4 inches. -D -1.0000 Ø How deep should she mill the 90° grooves so that the top of the sine block is 2 inches tall? The depth of the mill should be inches.
Complete solution and correct units pls. Draw the figures if necessary

She has a 1.250-inch-thick bar that needs 90° grooves machined into it for precision ground 1.0000-inch diameter cylinders. A sine bar is used by placing different thicknesses under one of the cylinders so that the proper angle is attained. Sally wants the distance between the centers of the cylinders to be D = 5.6 inches. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. -1.0000 Ø Once her sine block is finished, she wants to mill a 22.5° angle on a brass block. What thickness of gage blocks will produce this angle for this sine plate? (Round the final answer to four decimal places.) The required thickness is inches.
