1: The cantilevered beam is subjected to the load at its end shown in figure below.
Determine:
a) Principal stresses and the angle of plane in the beam at point A & B by analytical method.
b) Principal stresses and the angle of plane in the beam at point A & B by graphical method.(Construct Mohr'sCircle)
2. The shaft is supported at A by a journal bearing that exerts only vertical reaction on theShaftand at B by a thrust bearing that exerts both horizontal and vertical reactions on the shaft, draw the bending momentdiagram for the shaft and then from this diagram sketch the deflection or elastic curve for the shaft's centre line.
Determine: The deflection at x1 = x2 = 100mm and assume E= 200 GPa and diameter of the shaft is 20 mm, as shown in the figure below
3. The steel bar AB has rectangular cross section. If it is pin connected at its ends, Determine: The maximum allowable intensity 'w' of the distributed load that can be applied to BC without causing the bar AB to buckle. Use factor of safety with respect to buckling F.S.= 1.5, Est =200 GPa, σy= 360 MPa.
Twenty pounds of a gas mixture is contained in a tank with volume 30 cubic feet at 30 psia and 70 F. The gas mixture has volumetric analysis of twenty percent carbon dioxide, thirty percent oxygen, and fifty percent nitrogen.
piston cylinder device contains 0.06 m3 of saturated water vapor at 350 KPa pressure. Determine the temperature and the mass of the vapor in.
0.75 kg of Refrigerant 134-a is compressed in a compressor from 160 kPa and -10°C to 1.2 Mpa and 50°C, steadily. Determine the change in flow exergy of the refrigerant during this process, if the environment is at 100 kPa and 25°C.
Design an SI engine operating on an four-stroke air-standard cycle using stoichiometric gasoline is to have a maximum cylinder pressure of 11,000 kPa at WOT. Inlet pressure can be 100 kPa without supercharging, or it can be as high as 150 kPa with a ..
water at 4oc is to be delivered to the top of a ski area for snowmaking purposes. the water is to be drawn from a
A pump is employed to deliver liquid water from a pond to a higher elevation. The pump steadily draws water from the pond at a volumetric flow rate of 192 gal/min through a pipe having a 7 in diameter inlet. The exit diameter of the pipe is 2 in. and..
Air at 300 kPa, 63oC, and a velocity of 423 m/s enters an insulated duct of varying cross-sectional area. The air exits at 150 kPa, 88oC. At the inlet, the cross-sectional area is 6.57 cm2.
a rigid tank initially contains 3 kg of air at 500 kpa 290 k. the tank is connected by a valve to a piston-cylinder
Air enters a nozzle steadily at 50 psia, 140°F, and 150 ft/s and leaves at 14.7 psia and 900 ft/s. The heat loss from the nozzle is estimated to be 6.5 Btu/lbm of air flowing. The inlet area of the nozzle is 0.1 ft^2. Determine (a) The exit temperatu..
a cross section of a rotating bearing is shown. the spherical member rotates with angular speed omega a small distance
past car sales experience has shown that 18 of all luxury cars sold are black. if 48 recent sales of luxury model cars
An axially symmetric space vehicle with It/Ia= 10 is undergoing a general torque-free motion. The angle between the angular momentum vector H and the axis of symmetry is 45 deg.
