The beam is subjected to the distributed loading. Determine the length b of the uniform load and its position a on the beam such that the resultant force and couple moment acting on the beam are zero.
Given:
w1 = 40lb/ftc = 10ft
w2 = 60lb/ft = 6 ft
A 2.45 m wide rectangular channel has a bed slope of 0.0004 and Manning's roughness coefficient n of 0.015. For a discharge of 2.83 m^3/s, determine the type of water surface profile for depths of 1.52 m, 0.61 m, 0.30 m.
When using singularity functions, if I have a reactionary moment at a cantilever connection, do I use the right hand rule to solve the moment and determine it's direction through the reactions
A number 10 (No. 10) steel rebar is tested in tension. By monitoring the load reading of the testing machine, it was found that the specimen yielded at a load of 41,600 lb and fractured at 48,300 lb.
Steam at 800 kPa and 300 C is bled off from a large supply line, passed through a valve, and allowed to enter an initially evacuated, uninsulated tank with a volume of 0.3 m3.
water at 150 degrees in a beaker is placed in an airtight chamber. Air is gradually pumped out of the container. What reduction below atmospheric pressure of 14.7 psi must be achieved before water boils
A curve of radius 300 ft and e = 10% is located at the section of an existing rural highway, which restricts the safe speed at this section of the highway to 40% of the design speed.
Are either of the Ax or Jx forces relevant to finding the tension between H and J. If so, what is the easiest way to solve for those 2 unknowns.
Water flows downhill through a 3 in. diameter steel pipe. The slope of the hill is such that for each mile (5280 ft) of horizontal distance, the change in elevation is Δz.
A polycrystalline Al alloy contains a dispersion of hard particlesof diameter 10-8m and average center to center spacingof 6x10-8m measured in the slip planes. Estimatetheir contribution to the tensile yield strength,σy, of the alloy.
The channel has side slopes of 4H:1V and a longitudinal slope of 0.5%. Assume a depth of flow of 6-inches. The parking lot slopes at 1% toward the channel from both sides, and the 2-year, 24-hour rainfall is 2in.
A gate (shaped like .25 of a cylinder with radius R=3m) is used to control the flow of water through a canal.The height of the water in the tank is 30m. How much force must be applied to keep the gate from opening? The gate is 30m wide.
Sketch the flow field defined by u=3y, v=2 and derive expressions for the x and y components of acceleration. Find the magnitude of the velocity and acceleration for the point having the coordinates (3,4). Specify units in terms of L and T.
