A simply supported span of 28 feet must carry a uniform loading that produces a total factored maximum moment of 300 K-ft including the beam weight. The concrete can be 3.5 ksi and the steel is grade 60. You can design the beam as a single reinforced, double reinforced or an isolated ‘T' type beam as far as the architecture is concerned, but the beam width must be 24in.a. Sketch a shear diagram for this beamb. If the effective depth was assumed to be 14in, determine the maximum design shear force for the given loading.c. Again assuming d=14in, determine, or at least show exactly how to determine, the portion (length) of span of the subject beam which theoretically would require no shear reinforcement.
Assume that there were 1,100,000 vehicles making a 28.5-mi round trip per day, the average vehicle emission rate for VOCs is 1.3 g/VM , and the molecular weight of the VOC emissions from the mobile sources can still be represented by that of metha..
using the principles to developed in chapter 3 on equilibrium, one can determine that the tension in cable AB is 143.4 N. Determine the moment about the x-axis of this tension force acting on point A.
World population reacted 4billion in 197 Use the doubling time approximation (3.5) to estimate the exponential rate of growth that would produce those numbers. Use the exponential growth equation (3.6) to find the growth rate
A model grain dryer is being used to investigate the drying process. It is discovered that the load cell which supports the dryer indicates that the mass of the dryer and its contentsinitially increases during the heat-up.
The efficiency of the engines of subsonic airplanes depends on air pressure and usually is maximum near about 36,000 ft. Find the air pressure y(x) at this height. The rate of change y(x) is proportional to the pressure
