1) A reinforced concrete beam has square cross section (h × h). There are 4 steel reinforcing bars (each of diameter ds). The reinforcement is symmetrically placed in each corner of the beam section, such that thedistance from the centre of the bar to any edge of the section is e. It should be taken that ρsteel = 7800 kg/m3, ρconcrete = 2450 kg/m3, Econcrete = 35000 MPa and Esteel = 200000 MPa, and that both materials exhibit linear elastic behaviour. The concrete cracks in tension at 10 MPa. The beam can beconsidered as a cantilever beam of length L. Given h=375 (mm) ds=20 (mm) e=35 (mm).a) What is the self weight per unit length of the beam?b) Under self weight only, calculate the length of the beam (L) such that it just cracks under its self weight.c) Now consider the same beam with the same length but it is now a simply supported beam. An additional point load, P, is then applied at midspan. What value of P (in conjunction with self weight) will induce cracking? Draw the stress and strain distributions for both the steel and the concrete onthe critical cross-section just prior to cracking.

Pinion gear A rolls on the fixed gear rack B with an angular velocity = 8 rad/s. Determine the velocity of the gear rack c . Assume the direction to the right as positive.
Two different fluids flow over two identical flat plates with the same laminar free-stream velocity. Both fluids have the same viscosity, but one is twice as dense as the other. What is the relationship between the drag forces for these two plates
A chemical is added at the beginning of a water treatment plant at a dose of 750 lb/day. The water treatment plant provides water to a community of 200,000 people and the average water consumption in the city is 110 gallons per capita per day (gpcd).
consider the cantilever beam-mass system. formulate and solve the minimum weight design.
A trapezoidal channel of bottom width 25ft and side slope 1:2.5 carries a discharge of 450cfs with a normal depth of 3.5 ft. The elevations at the beginning and end of the channel are 685 and 650 ft, respectively.
Base course aggregate has a target dry density of 119.7 lb/cu ft in place. It will be laid down and compacted in a rectangular street repair area of 2000 ft*48ft*6in.
A "slap shot" in the game of hockey can cause an increase in the velocity of a 5 oz puck from 2 ft/sec to 110 ft/sec. What would be the corresponding increase in the kinetic energy (ft-lb) of the puck.
