the suspended load exerts a force F=600 lb at A, and the weight of the bar OA is negligible. Determine the tensions at the cables and the reactions at the ball and socket support O
It is necessary to design a square-section composite bar that will withstand an applied load without deflecting more than a specified amount.The design specification for the bar, including its dimensions and loading criteria, is given below.
find the total heat loss per m length of the steam line. Find also the temperature at the interface of steam and insulation.
A pump station has been designed to lift water out of a 6 metre deep pit (vented to atmosphere) via a centrifigual pump mounted at ground level. Calculate the Net Positive Suction Head (NPSH) for the system ?
rocket boosts the speed of a spacecraft from 7500 m/s to 10 500 m/s with a thrust of 890 kN. Calculate the rocket power.
Tensile force formulas, A cylindrical steel beam is 2 inches diameter and 6 feet long. The modulus of elasticity is 30 x 1,000,000 psi. If the beam is subjected to a tensile force of 1000 lbs, what will be the resulting unit strain?
In a tubular low pressure chemical vapor deposition (LPCVD) reactor, gas is introduced at one end at a rate of 75 torr-L/min. At the other end is a vacuum pump of a speed Sp. If the reactor must operate at 1 torr, what value of Sp is required?
A layer of water seperates two smooth surfaces a distance of 2r. Derive an experssion for the force needed to pul the two surfaces apart. Consider the bottom surface fixed. What is the force needed to seperate the top surface?
What is the velocity and rate of flow of the metal into the mold? Is the flow turbulent or laminar? (Pure aluminum density ρ = 2.7 g/cm3).
Find the final state inside the tank, A tank contains 2kg of nitrogen at 10K with a quality of 50%.Through a volume flow meter and valve, 0.5kg is now removed while the temperature remains constant.
The mean diameter of a conical friction clutch is 250mm with a width of the conical surface being 50mm. The clutch is lined with a material having a coefficient of friction of 0.25
determine the coordinates xc and yc of the point where the resultant load must act in order to produce uniform normal stress in the column.
the traveling crane consists of a 5-m-long beam having a uniform mass per unit length of 20kg/m. The chain hoist and its supported load exert a force of 8 kN on the beam when x=2m. draw the shear and moment diagrams for the beam.
