A dc shunt motor is driving a constant-torque load at the rated speed and rated terminal voltage. The motor has the following rated data:
Terminal voltage = 115 V
Speed = 312 rpm
Field constant K(phi) = 3 V sec
If the terminal voltage of the motor is reduced by 10%, what is the motor speed? Assume that the field voltage is also reduced by the same ratio.

PET has a Young's, Modulus of 3.5 GPa and PLGA 1.2 GPa. A polymer blend is prepared with 50:50 mixture (PET:PlGA) . What is the Young's, Modulus of this blend (use mixture rule). Calculate the percent load borne by PET when the blend is subjected to a load. If after 10 days, half of PET and one third of PLGA had degraded, what is the Young's Modulus of this blend.

A locomotive semi-elliptical laminated spring has an overall length of 1 m and sustains a load of 70kN at its centre. The spring has 3 full length leaves and 15 graduated leaves with a central band of 100 mm width. All the leaves are to be stressed to 400 N/mm2 when fully loaded. The ratio of the total spring depth to that of width is 2. E = 0.2 x 106 N/mm2. Design leaf spring.

The pressure difference p of air that flows through a fan is a function of the diameter D of the blade, its angular rotation, density of the air, and the flow Q. Use the FLT method of repeating variables to generate a dimensionless relationship between these parameters

The wing on the aircraft in Figure below is subjected to a drag FD
created by airflow over its surface. It is anticipated that this force is a function of the
density and viscosity of the air, the characteristic, length of the wing, and the velocity
of the flow. Show how the drag force depends on these variables by using FLT
system.

A simply supported bridge shows below is the primary path for the village people
to travel to the city centre. In the following case, the loading from the bus (5000
kg) and truck (3000 kg) can be treated as concentrated loads and the three private
cars (1500 kg each) can be treated as evenly distributed load. Your supervisor asks
you to find out the reaction forces in both simply supported at the end of the
bridge
