1.A flexure test is done to determine the modulus of rupture of wood. Given that a=15in, L=34in, and the maximum load P that was applied was 5950lbf, what is the modulus of rupture of wood?
2.The space truss shown is supported by a ball-and-socket joint at D and by short links at A and C. Determine the support reactions and the force in each member of the space truss.
The acceleration of a particle is defined by the relation a=-8m/s^2. Knowing that x=20m when t=4s and that x=4m when v=16m/s, determine (a) the time when the velocity is zero, (b) the velocity and the total distance traveled when t=11s.
a gate having cross section shown in fig closes an opening 5 ft and 4 ft high in a water reservoir. The gate weighs 400lb and its center of gravity is 1 ft to the left of AC and 2 ft above BC. Determine the horizontal reaction that is developed on..
What is the displacement and acceleration of the automobile at t-15, 45, and 50 seconds. Construct a v--t graph from 0 to 50 seconds.
Suppose that in an apparatus it is necessary to maintain precisely the cross section of a 20mm circular nickel steel bar. If this bar is heated to 200 deg Celcius
Determine the horizontal component of reaction that the pin A exerts on the two-member frame. Set F = 500 (Find Ax) Determine the vertical component of reaction that the pin A exerts on the two-member frame.
Determine a set of rectangular beam design values (b),( d) and (As) area of steel, that will be needed to support a factored bending moment (Mu=450 Kip-ft). Use (f'c=4,500 psi) and (fy=40,000 psi).
the break up of a liquid jet into droplets of diameter d depends on the jet diameter d the jet velocity v viscosity mu
Assume that the sewer flow and the stream flow are completely mixed, that the salt is a conservative substance (it does not react), and that the system is at steady state.
Chromium contamination is a problem at a number of hazardous-waste sites. At one site local concentrations of chromium reached 60,000 mg chromium/kg soil and 19,000 mg/L chromium in the water.
What is the shear rate in the water between a sliding and standing plate, if V = 10 ft/s is the moving plate velocity and 0.1 in. is the distance between the plates
The electric pole and the stub pole are at the edges of the roadway right-of-way. The anchor will be outside of the right-of-way and will require the subdivision to purchase land from the neighbouring farmer (who is VERY UNHAPPY about the subdivis..
Design a simply supported one-way reinforced concrete floor slab to span 10 ft and carry a service live load of 175 psf and a service dead load of 25 psf. Use fc' = 3000 psi and fy = 60,000 psi. Make the slab thickness to ½-in. increments.
