in. diameter, 20 in. length, steel and aluminum bars are fitted between rigid plates(" just touching") at 70 F. The bars are then heated from 70 F to 300 F.
1. Calculate the axial stress in each bar.2. Calculate the change in diameter in each bar.
The bottom bar is made up of an aluminum bar and a steel bar, each 10 in. long placed in the parallel configuration at 70 F. That is also heated to 300 F.
1. Calculate the axial stress in each bar.2. Calculate the change in diameter in each bar.3. Calculate the new location of the interface - does it move left or right and how much?
Determine the Stoichiometric oxygen requirement (pounds of oxygen per pound of fuel) for a fuel containing by weight 50% n-octane,25% 1-heptene and 25% methanol.
If direct runoff hydrgraph derived from a unit hydrograph of a catchment (drainage area = 50 acre) is 120 acre-ft, back calculate the rainfall amount. Assume total abstraction in the area is 50%.
A cutting 9 m deep is to be excavated in saturated clay of unit weight 19 kN/m3. The design shear strength parameters are cu = 30 kN/ m2 and fu = 0. A hard stratum underlies the clay at a depth of 11 m below ground level.
Determine the velocity of slider block C at t=0, (b) the acceleration of A and C, (c) the change in position of block A after 5s.
a freeway exit ramp has a single lane and consists entirely of a horizontal curve with a central angle of 90 degrees and a length of 628 ft. if the distance cleared from the centerline for sight distance is 19.4ft, what design speed was used
An industry discharges .5m^3/s of waste with a 5 day CBOD of 500 mg/l to a river with a flow of 2 m^3/s and a 5 day CBOD of 2 mg/l calculate the 5 day CBOD of the river after mixing with the waste.
Find the volume of the solid S. The base of S is the region enclosed by the parabola y=4-3x^(2) and the x-axis. Cross sections perpendicular to the y-axis are squares.
A three-point bending test is performed on a glass specimen having a rectangular cross section of height d=5mm and width b=10mm; the distance between support points is 45mm.
Calculate the distance d from the center of the earth at which the force on a particle from the moon is equal to 1.49 times the force on the particle from the earth. The particle is restricted to the line through the center of the earth and the mo..
