Write a computer program that, for an area with known moments and product of inertia Ix, Iy, and Ixy, can be used t obtained by rotating the original axes counterclockwise through an angle θ. Use this program to compute Ix, Iy, and Ix , y for the section of Sample Prob. 9.7 for values of u from 0 to 90° using 5° increments.
Prob. 9.7 Determine by direct integration the moment ofinertia of the shaded area with respect to the x axis.
a manometer is connected to a water pipe to measure the pressure at the center of the pipe. the manometer is
A fan jumps into a swimming pool in an attempt to drown her sorrows. She is able to float on her back...in a position that is neutrally buoyant...so that she can continue to breathe through her mouth. Believing that 70% of her body is composed of wat..

a four cylinder four stroke diesel engine has a bore of 212 mm and a stroke of 292 mm. at full load at 720 revmin the
(1) I shte cooling process polytropic? If so, what is the value of n? (2) Find the final state pressure. (3) Compute the work done for this process considering the water as a closed system.
The electrical conductivity of the pipe ke is constant over the temperature range of interest. The local rate of electrical heat production Se is then uniform throughout the pipe wall.
refrigerant 134a enters a compressor at 200kpa 100 quality and exits at 1mpa 60 degrees centigrade. the speed of the
A wall consists of two layers of insulation pressed against each other. Do we need to be concerned about the thermal contact resistance at the interface in a heat transfer analysis or can we just ignore it?
Assuming nucleate boiling conditions calculate the temperature of the bottom surface of the pan.
a 1 kg sample of water vapor initially at 300 kpa and 250 degrees c cools at constant pressure with no internal
An ideal duct carries water (incompressible fluid) from a height of 10m to 20m. The pressures at the entry and exit points are at 1000 Pa and 2000 Pa respectively. Calculate exit velocity if the velocity at entry is 10 m/s.
