Three cross-sections are extruded using an extrusion press. The first cross section is an isosceles right triangle of perpendicular sides of length 0.5 inch and 1.2 inch. The second is an equilateral triangle of side 1.5 inches, the rectangle of sides 0.9 inch and 1.2 inch. Calculate the CCD for each cross-section. Determine the shape factor for each crosssection. If the original billet is of 4 inches diameter, calculate the extrusion ratio for each case.

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
