A steel rod to which three disks are attached is shown below. The rod is fixed against rotation at its left end, but free to rotate in a bearing at its right end. Each disk is 300mm in diameter. Calculate the maximum shear stress in each segment of the rod. What is the angle of twist of section A relative to the fixed section E? Also draw a diagram for the angle of twist vs. position, showing the angle of twist for every position in the rod. (G=80Gpa)
A 20 kg package is at rest on an incline when a force P is applied to it. Determine the magnitude of P if 10 seconds is required for the package to travel 5 m up the incline. The static and kinetic coefficients of friction between the package and ..
Lift Charts in direct marketing, The mass-mailing business is often used to illustrate the use of lift charts. Another real world application where the lift charts can be used
Determine the air pressure at the top of a 300 m high building by assuming the density of air stays constant at the z = 0 value. Now compute the pressure assuming the density of the air varies. Is there a significant difference.
The testing machin that covers the right range of load is to be chosen. it is expected to load the material up to a strains of 3%. if th material must remain elastic over that range, what would be the maximum load
Water occupies the bottom 0.8 m of a cylindrical tank.On top of the water is 0.3 m of kerosene, which is open to the atmosphere. If the temperature is 20 degrees C, what is the gage pressureat the bottom of the tank
An air-water vapor mixture at 0.1 MPa, 35 C and 70% relative humidity occupies a volume of 100 m^3 Determine the humidity ratio, the dew point, the mass of dry air in the volume and the mass of water vapor in the volume.
IF the bulk density of coarse grained soil is 1760 kg/m^3 what is its void ratio, e, and saturation, S. Draw the complete phase body diagram and show the masses and volumes.
A firm's stockholders expect a 15% rate of return, and there is a $12M in common stock and retained earnings. The firm has $5M in loans at an average rate of 7%. The firm has raised $8M by selling bonds at an average rate of 6%
The coefficient of static friction between each crate and the ground is 0.25 The crates are next to each other connected by a rope and then from the other end one has a P force going up at an angle of 30 degrees
The truck is driving onto the stationary barge at the speed of v1. The masses of the truck and the barge are m and M, respectively. The barge is free to move on the water and the water resistance is to be ignored.
Air enters a steady flow, adiabatic compressor at 17 °C and is compressed through a pressure ratio of 8.6: 1. Assuming the compressor to be internally reversible
