a force acting 45 degrees below the negative x-axis is equivalent to a force acting litosphere

1. Calculate the definite integral

123ta+2ebt+1t+2ct dt

A simply supported beam of 12 m length carries two point loads 58 kN and 54 kN

at 3 m and 8 m respectively from the left hand end. Find the deflection under each

load and the maximum deflection. Take I=190X10

6mm4 and E=200 GPa.

Define fatigue and specify the conditions under which it occurs.

A simple manometer is used to measure the pressure of oil (sp. gr. = 0.8) flowing in a pipeline. Its right limb

is open to the atmosphere and left limb is connected to the pipe. The centre of the pipe is 9 cm below the

level of mercury (sp. gr. 13.6) in the right limb. If the difference of mercury level in the two limb is 15 cm,

determine the absolute pressure of oil in the pipe in N/cm2

An ideal double-reheat steam turbine receives 300,000 kg/h of steam at 10 MPa and 400°C. After expansion from high pressure turbine shell, it is reheated twice from saturated vapor condition back to its initial temperature. The steam entering the condenser is 97% dry. Determine (a) engine work, (b) engine thermal efficiency, and (c) steam rate. (d) Considering a generator output of 100 MW with 97% generator efficiency, what are the combined heat rate, (e)brake work, (f) brake thermal efficiency, and (g)pump power

requirement.
