A 1 cm × 20 cm sheet of water is deflected as shown in the digram.The magnitude of the total force acting on the stationary deflector is nearest:

A 1500-lb force F is applied at a point in a body as shown in the diagram

A 1500-kg race car is driven at a speed of 150 km/hr on a circular race track of radius 50 m. What frictional force must be exerted by the tires on the road surface to keep the car from skidding?

A 16-bit ripple carry adder is realized using 16 identical full adders (FA) as shown in the figure. The carry-propagation delay of each FA is 12 ns and the sum-propagation delay of each FA is 15 ns. The worst case delay (in ns) of this 16-bit adder will be?

A 15-cm-diameter aluminum ball is to be heated from 80°C to an average temperature of 200°C.

15 hp, 240 V, 1780 r/min dc series motor has a full-load rated current of 54 A. Calculate the current and speed

A 15-ft beam weighing 500 lb is lowered by means of two cables unwinding from overhead cranes. As the beam approaches the ground, the crane operators apply brakes to slow the unwinding motion.

A 100 eV hydrogen ion is released in the center O of the plates in the coordinate system as shown in the diagram.

A 100-ft length of surveyor’s tape weights 0.6 lb. When the tape is stretched between two points on the same level by a tension of 10 lb at each end, calculate the sag h in the middle.
