A bowling ball has a mass of 6 kg, a moment of inertia of 1,6 10^{-2} kg.m^{2}, and a radius of 0,2 m. If it rolls down the lane without slipping at a linear speed 8 m/s, what is its total energy?

Choose any real time structural or machine component, part, and member subjected to loading

that you are familiar with (e.g. a beam). The chosen problem should be complex enough that you can

write something about it, but not so complex that you get bogged in a lot of details.

Thorough analysis is expected in terms of:

a. Problem statement with design limitations, requirements with assumptions.

b. Complete analytical calculations with proper description

c. Proper drawing of the component, part or member with dimensions and application of loads.

d. Free body diagram, shear force diagram, and bending moment diagram wherever necessary.

e. Normal and shear stress distributions wherever applicable.

f. Factor of Safety.
