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= 5.9 inches. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. 7 -1.00000 * How deep should she mill the 90° grooves so that the top of the sine block is 2 inches tall? (Round the final answer to four decimal places.) The depth of the mill should be 7071.067 inches.

Select all the correct statements: a. Moment of force or toque is force multiplied by the perpendicular distance from the point of application of the force to the selected point or center. b. The perpendicular distance is also termed as moment arm. C. The axis of the moments and the planes of the forces are intersecting at the center of the moment. d. Graphically, the moment can also be defined as the area of the triangle formed by joining the center of moments with the ends of the forces. B
