Orbits in general relativity :
In the theory of general relativity, the path equation for a planet moving in the gravitational field of the Sun is, in the standard notation,
(d2u/dθ2) + u = (MG/L2) + (3MG/c2)u2,
where c is the speed of light. Find an approximation to the ‘annual' advance of the perihelion of a planet moving in a nearly circular orbit of radius a.
a heat engine supposedly receives 500 kjs of heat from an 1100-k source and rejects 300 kjs to a low-temperature sink
Determine the bending moment M in the pinned-end column with eccentric axial loads shown in the figure. Then plot the bending-moment diagram for an axial load P= 0.3Pcr.
Based on the information discussed in fender design and ships characteristics, estimate the size and number of fenders that will be required for budgeting purposes. Basis for selection of vessel characteristics and fender type must be discussed to..

a mass of 1 kg of air contained in a cylinder at 1.5 mpa 1000 k expands in a reversible isothermal process to a volume
A punch press, used for stamping sheet metal, has a punching capacity of 50 kN. The section ofthe frame is as shown in Fig. Find the resultant stress at the inner and outer fibre of the section.
Water at 20-C ?ows over a 3-m long and 2-m wide ?at plate at 3 m=s. Assume a turbulent ?ow from the leading edge (a trip wire at the leading edge can be used to cause the turbulence) and calculate:
