A tank (m = 50,000 kg) is at rest while on the inclined part of a bridge, as shown. The angle of inclination of the bridge is 25 degrees. a) What is the weight of the tank on Earth? b) How should the FBD of the tank look like? (Draw the complete FBD, including components, labels, and angles.) c) How should a completely filled-out table of components for the forces on the tank look like? Show the complete table of components, with solutions on the side.

b) How should the FBD of the tank look like? (Draw the complete
FBD, including components, labels, and angles.)
c)
How should a completely filled-out table of components for the
forces on the tank look like? Show the complete table of
components, with solutions on the side.
d) How much normal force is exerted by the floor on the tank?
e) How much friction is exerted on the tank by the floor?
f)
What is the coefficient of static friction between the tank's "wheels" and the bridge's
floor?
