Each of the two uniform slender bars OA and BC has a mass of 8 kg. The bars are welded at A to form a T-shaped member and are rotating freely about a horizontal axis through O. If the bars have an angular velocity ω of 4 rad/s as OA passes the horizontal position shown, calculate the total force R supported by the bearing at O.
A $325,000 bond has an interest rate of 8.4% but if the bond experiences an inflation rate of 8.6% what will be the profit be after 4 years
Determine the support reactions at the pin joints A, E and I for the following three pin frame and determine the bending moment at the knees at C and at G. Also determine the shear in the horizontal beams just next to the knee joints. Place half t..
For each of the two cases below, determine the water pressure, pressure head, elevation head, and total head at points A, B, and C. Please solve the problem using: (a) the upper reservoir level as the datum
a whirlpool is modeled as the combination of a free and a forced vortex. the maximum velocity in the whirlpool is 10 m/s, and the radius at the juncture of the free and the forced vortex is 10m.
A sample of aggregates weighs 400 grams. After drying at 112oF, its weight was 398.5 grams and absorption is 10%. Determine the moisture content and the free moisture.
A level is set up midway between two wood stakes that are about 300 feet apart. The rod reading on Stake A is 9.65 ft and the reading on stake B is 4.23 ft. The level is then set up 6 feet in front of stake B.
The 24-in pipe leads from a reservoir (flush entrance), and the 18-in pipe discharges into the air at a point 15 ft lower than the reservoir water surface level. Assuming all changes in section to be abrupt
The number of teleport inquires x in a time sharing system average .2 millisecond and follows a Poisson distribution. Find the probability at least one inquiry is made during the next millisecond.
A 2.0m-wide strip at a depth of 1 m in a stiff clay carries a wall load of 425 kN/m. The saturated unit weight of the caly is 20kN/m^3. TRiaixal tests give the following results: c'=10 kPa, phi'=28 degree, cu=105kPa, and phi_u = 0.
Water at 20 °C is transported through a 200 m long wrought iron pipe with a head loss of 9.8 m. Determine the diameter of the pipe required to convey 10L/sec.
Consider two cases: (1) a constant wind velocity that is twice the mean wind velocity and operating half the time; and (2) a constant wind velocity that is three times the mean wind velocity operating one-third of the time. At all other times, the wi..
Determine a composite SCS runoff curve number for a 600-acre basin that is totally within soil group C. The land use is 40 percent contoured row crops in poor hydrologic condition and 60 percent native parture in fair hydrologic condition.
