A steel bar with the cross section shown and effective length L = 2.5 m is subjected to a compressive load P = 200 kN with a eccentricity e = 0.00625 m. Find
(a) the beam's maximum deflection, and
(b) the maximum normal stress.
A pipe transports water in a 4-cm-diameter pipe with an average velocity of 10 m/s. The pipe undergoes a 90 degree bend and exits out a 2-cm-diameter nozzle. Assuming no friction losses in the bend, the total force of teh water on the bend is nearest..
1. Determine the volume change, in ft3, when 1 lb of water, initially saturated liquid, is heated to saturated vapor while pressure remains constant at 1.0, 14.7, 100, and 500, each in lbf/in.2 Comment. 2. For H2O, determine the specified property..
What is the minimum optical power level that must be launched into the fiber to maintain an optical power level of 2.0 auW at the receiving end. What is the required input power if the fiber has a loss of 0.6 dB/km
Determine the temperature at which the diffusivity D of Cu in Al is twice the diffusivity at 500K. Using your result for D of Cu in Al at 500K, estimate the distance that a Cu impurity would diffuse in Al at 500 K after 1 hour. Use the simple estimat..
A reversible heat engine receives heat from a heat source at 1000oC and has a thermal efficiency of 45%. The heat engine does maximum work equal to 600kJ. Determine the heat supplied to the heat engine, heat rejected to the heat sink, and the tempera..

a gate in the shape of a quarter cylinder hinged at a and sealed at b is 3 m wide. the bottom of the gate is 4.5 m
a cantilevered beam bracket of uniform cross section extends 12 inches from the wall and supports 100 pounds of load at
Consider a 4-in square steel bar subjected to transverse biaxial tensile stresses of 20 ksi in the x direction and 10 ksi in the y direction.
in a machining operation an 8 minute tool life was achieved at a cutting speed of 500 fpm. at a cutting speed of 250
A gas turbine receives a mixture having the following molar analysis: 10% CO2, 19% H2O, 71% N2 at 720 K, 0.35 MPa and a volumetric flow rate of 3.2 m3 /s. The mixture exits the turbine at 380 K, 0.11 MPa. For adiabatic operation with negligible kinet..
A wind turbine with a diameter of 100 ft operates during a 24-h period in which the wind velocity may be approximated by half a sine wave as V(theta)=V(m)sin(pi*theta/24), where theta is time in hours and V(m)= 10^5 ft/h. The wind density is 0.076 l..
