A beam of w16 X 50 section has a simple span of 20 ft. The beam is subjected to a uniform load of 2 kips/ft and an axial tensile force of 10 kips. Determine the maximum tensile and compressive stresses in the beam
The initial concentration of carbon in the metal is 0.1wt%. We first do an experiment by applying a concentration of 5%wt of carbon at the surface of a similar slab and maintaining the system at 900 K for an hour.
A round bar of 6mm diameter is made of 6061-T6 aluminum. When the bar is stretched by an axial force P, its diameter decreases by 0.450 microns. what is the magnitude of the load P
A pig farmer owns a 20-arce farm and started business with 22.1 pigs. After one year, he has 319 pigs. Assuming a constant growth rate, what is the doubling time in units of days.
A jet of water of diameter 75mm moving with a velocity of 25m/s strikes a fixed plates in such a way that the angle between the jet and plate is 60 find the force exerted by the jet on the plate.
Water is flowing in a 6-cm diameter pipe at 20 m/s at 10?C. If the pipe enlarges to a diameter of 12-cm, calculate the reduced velocity. Also, calculate the mass flux rate and the flow rate.
The uniform load has a mass of 400 and is lifted using a uniform 40- strongback beam and four ropes. determine the tension in each rope
A two stage rocket with a total mass of 925kg is traveling at a speed of 6.6 10^3 m/s away from the earth . A predesigned explosion separates into two sections of equal mass that move with a speed of 2800m/s relative to each
Should Bernard bid for the project assignment? Why or why not? Does Bernard have an unfair advantage over firms having designed the project on which he wants to bid?
What is the maximum population that can be served by a 900 mm diameter main sewer constructed on minimum grade. If sewage flow in the pipe never exceeds a depth of 600 mm, estimate the actual population contributing flow to the main.
Water is contained in a pressurized tank to a level of z meters above the ground. the air pressure over the water surface (in the tank) is 135kPa (abs). Assume the water density is 1000 kg/m^3 and take g=9.807 m/s^2.
