Q.1 Derive an expression for the deflection due to shear for a cantilever beam of constant rectangular cross section, under action of a point load, P at free end.
Q.2 Show how the max shear stress occurs at the neutral axis and a value of 3/2 x average shear stress on the section.
Q.3 If length of cantilever is 2m, P=100KN, b=100mm, d=200mm, E=7.5 KN/mm2, calculate the shear deflection at the free end.
To float a 160 pound man using helium balloons (assume 0.52 cubic feet per inflated balloon). How many balloons would it take? Assume density of air is 1.29 kg/cubic meter and the density of helium is 0.179 kg/cubic meter.
Determine the deflection of the right end of the pointer and the maximum deflection of the beam.
At the end of 15 years, the first motor will have a salvage value of $50 and the second motor will have a salvage value of $100. consider the MARR to be 8%. (note : 1HP=0.7457 kw). Determine which motor should be installed based on the PW criterio..
Two immiscible fluids are in contact. Fluid I is denser and is also well mixed. The concentration of species a is cao everywhere within this fluid and the temperature in fluid I is held constant at To.
Determine the cycle time for a single engine scraper rated at 21 cy heaped that is used to haul material from a pit to a fill 900 ft away under severe conditions. The average haul speed will be 14 mph and the average return speed will be 20 mph.
The calculation and layout of horizontal and vertical curves should be done only by experienced surveyors and differential leveling measurements
Axis of the hole is perpendicular to VP. Draw elevation, plan and development of the lateral surfaces of the pyramid.
If friction between the cars and the rails is neglected, what were the magnitude and the direction of the velecity of the cars after the collision?
Calculate the numbers of married men, single men, married women and single women. Print these numbers on a student summary report. If any single men are over 30 years of age, print their names and ages on a separate eligible bachelors report.
A ten-foot high wall will retain a medium dense sand backfill. Determine the Rankine earth pressure diagram and the total active force on the wall.
Find the time for one complete cycle of this motion if the spring constant is 21 N/m. (Assume that once the pendulum ball hits the spring there is no effect due to the vertical movement of the ball.)
Calculate the tensile modulus of elasticity for a 10 laminated composite consisting of 62 percent by volume of unidirectional carbon fibers and an epoxy matrix under isostress conditions.
