Three cross-sections are extruded using an extrusion press. The first cross section is an isosceles right triangle of perpendicu
lar 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.

Answer:
Zero
Explanation:
Total energy of the EARTH is the sum total of the all the kinetic and the gravitation potential energy of the earth.
Which can be written as
At very large distances the kinetic as well as the gravitational potential energies become zero.
therefore, E_total= 0
