The answe to the above poll is
Increases- For a given cross section and young's modulus, buckling load and Slenderness ratio are inversely proprtional. So when slenderness ratio will increase then buckling load has to decrease which means the object will have more chance to buckle.

Hagen–Poiseuille equation gives head loss in a pipe having laminar flow. From the equation we can conclude that head loss is inversely proportional to d^4.

In Simplex, the condition of degeneracy will be when one or more than one basic variable should be 0.
Such that number of variables will be less than number of equations which will create Degeneracy.

The answer to the above poll is
2 Decreases- Pressure generally is applied by fluids, solids cannot apply pressure they induce stress always.
So, by using continuity equation and Bernoulis equation we will get that Area increases pressure increases which happens in Diffuser and vise versa in Nozzle.

The answer to the above poll is
2 Axial Pump
The diacharge of axial flow pump is more than centrifugal pumps. So we will use Axial flow pumps to delog water at a faster rate.

The answer to the above poll is
3 Mechanical Efficiency - Higher the mechanical efficiency, very less will be the frictional power. Indicated power is the power available at the piston and if the friction is high so mechanical efficiency will be very less.

The answer to the above poll is
1 Inner side
Because both the direct shear stress and the twisting couple stress are in the same direction in inner side whereas in outer side both the stresses are in opposite direction.
So inner side of the spring is critical.

Which will have more power loss
The answer to this poll is
3 Equal in both
Friction depends upon normal reaction so for eg having 5 collars, bearing 100N load so each collar will bear 20N so the net sum of friction will be equal in both hence power loss will be equal in both.
But single collar bearing will wear out faster than multicollar bearing.

The answer to this poll is
1 Yes
Power loss is given by Coefficient of friction *V*load
Coefficient of friction when calculated by Petroff's has load in denominator which gets cancelled so power loss is independent of load.
