a shaft is made of a steel alloy having an allowable shear stress of 12 ksi. If the diameter of the shaft is 1.5 in., determine the maximum torque T that can be transmitted. What would be the maximum torque T' if a 1 in. diameter hole is bored through the shaft?
Knowing that the coefficient of restitution is 0.8 between B and C, and 0.5 between A and B, Determine the velocity of each car after all collisions have taken place.
A lap joint needs to be designed using 20-mm diameter bolts to carry a load of 120 kN on the connecting plates. If the shear stress in each rivet is not to exceed 90 MPa, determine the number of bolts needed.
draw the shear and bending-moment diagrams for the beam and loading shown and determine the maximum normal stress due to bending.
Estimate the blood pressure in each branch, assuming that blood vessels behave as rigid tubes, that we have frictionless flow, and that the vessel lies in the horizontal plane. What is the force generated at the branch by the blood? You may approx..
A load of lumber of weight W = 20 kN is being raised by a mobile crane. Knowing the tension is 20 kN in all portions of the cable AEF and that the weight of the boom ABC is 3 kN, determine (a) the tension in rod CD (b) the reaction at pin B.
A circular shaft is subjected to a torque Ta and a bending moment Ma. Assuming that the diameter of the shaft is d, determine the expressions for the principal stresses and maximum shear stress in terms of Ma, Ta and d.
State the sequence in which the cylinders operate on the operation of the start valve and show, with the aid of a schematic diagram, how an electronic controller could be included in the circuit to control the sequence of cylinder operations.
Find the approximate location of the laminar turbulent transition - what is the net heat removed by the air around the rod?
Product and Engineering Design Review
Calculate the steady state excess electron and hole concentrations as a function of distance into the semiconductor.
The tank cover is airtight, and the pressure above the water surface is 2 atm gage. The system is at sea level. Determine the max height to which the water stream could rise.
let it cool back to the outdoor temperature, pass it through a turbine, and discharge the cold air leaving the turbine into the house. from a thermodynamic point of view, is the proposed system sound?
