Given a rectangular column of dimension 650X450 mm is required to support axial dead load is 815 kN, axial live load is 680 kN, dead load moment is110 kN.m and live load moment is135 kN.m acting on the major axis. All loads in service condition. Concrete compressive strength is 27.6 MPa, steel yield strength is 410. Assume longitudinal reinforcement bar diameter 25mm and ties diameter is 12mm

By using ACI interaction diagram design the required longitudinal reinforcement

Design the required ties and sketch the column section with all necessary details

We cannot rule out that transformational leaders. who are not driven by ethical values, hold the power to exploit the motivation of value-driven followers for their own profit; a phenomenon corresponding to pseudo-transformational leadership or the ‘dark side’ of transformational leader- ship.” (Braun et al., 2013, p.28

A process fluid is pumped from the bottom of one distillation column to another, using a centrifugal pump. The line is standard commercial steel pipe 75 mm internal diameter. From the column to the pump inlet, the line is 25 m long and contains 6 standard elbows and a fully open gate valve. From the pump outlet to the second column, the line is 250 m long and contains 10 standard elbows, 4 gate valves (operated fully open), and a flow-control valve. The fluid level in the first column is 4 m above the pump inlet. The feed point of the second column is 6 m above the pump inlet. The operating pressure in the first column is 1.05 bara and that of the second column 0.3 barg. Determine the operating point on the pump characteristic curve when the flow is such that the pressure drop across the control valve is 35 kN=m2. The physical properties of the fluid are density 875 kg=m3 , viscosity 1:46 mN m2s. Also,

determine the power consumption under uniform acceleration

Two circular loops A and B have their planes parallel to each other.

Loop A has a current moving in the counter clockwise direction, viewed from above.

1. If the current in loop A decreases with time, what is the direction of the induced current in loop B? Will the two loops attract or repel each other?

2. If the current in loop A increases with time, What is the direction of the induced current in loop B? Will the two loops attract or repel each other?

A bar magnet falls through a circular loop .

(a) describe qualitatively the change in magnetic flux through the loop when the bar magnet is above and below the loop.

(a) make a qualitative sketch of the graph of induced current in the loop as a function of time, choosing current to be positive when it's direction is counterclockwise a s viewed from above
