a. Draw, to a reasonable scale, the influence line for the shear at C for the beam shown above. Label all critical values on the I.L.
b. Determine, using an influence line, the maximum downward reaction (A??c) at A due to a 2 kips/ft live load for the beam shown above.
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.
Find the velocity of the air downstream of the restriction, and show that the enthalpy is essentially the same before and after the throttling process. Also find the change of entropy.
Two sites, A & B, are being considered for the construction of a dam. Construction at Site A will cost $20 million and have an annual benefit of $2 million. Construction at Site B will cost $30 million and have an annual benefit of $3 million.
if each cord can sustain maximum tension of 50N before it fails, determine the greatest weight of the flower pot the cords can support
The compacted specimen contains 6% asphalt binder by weight of total mix, and has a bulk density of 143.9 lb/ft^3. Ignoring absorption, compute the percent voids in total mix, percent voids in mineral aggregate
Calculate the compression resistance of 200 UC 59.5 column which is 3.6 m high (between lateral supports). Both ends of the stanchion are held effectively in position but only one is also restrained in direction. Use grade 43 steel
A large rock became visible to a driver at a distance of 175 ft. Assuming a perception-reaction time of 0.8s, an initial speed of 42 mph, a coefficient of friction equal to 0.5, and a level roadway, calculate the speed at impact.
Compute stiffness terms K(1,1) and K(2,7) of a four node quadrilateral plane stress element using full and reduced numerical integration and Gaussian Quadrature - Show that the Jacobian is singular
A rectangular unfinished concrete channel with wood forms is laid on a bottom slope of 0.0064 to carry a flow of 20m^3/s of water. Determine the width of the channel when the flow is in critical condition.
A pressure cooker maintains a constant pressure while food cooks in a water-steam mixture. If the pressure is higher than atmospheric, the water in the cooker boils at a higher temperature and makes cooking faster.
