A short reinforced concrete column is subjected to a 1000kn axial compressive load.
The moduli of elasticity of plain concrete and steal are 25 GPa and 207GPa respectively, and the corss-sectionial area of steel is 2% of that of the reinforced concrete.
Considering the column as a structural member made of a composite material and subjected to load parallel to the steel rebars, calculate the following:
c. the minimum required cross-sectional area of the column given that the allowable comopressive stress of the plain concrete is 20MPa and that the allowable compressive stress of the plain concrete will be reached before that of the steel.
Knowing that the modulus of rigidity is 77 GPa for the steel and 27 GPa for the aluminum, determine the largest angle through which end A can be rotated if the following allowable stresses are not be exceeded
A steel flat bar of dimensions 4x1x12 inches is PINNED between two copper bars of dimensions 4x2x12 inches at room temp. The PINNED assembly is then cooled by 200 degrees fahrenheit.
the boiling point of water decreases wiht elevation because of the pressure change. what is the boiling point of water at an elevation of 2000m and at an elevation 4000 m for standard atmospheric conditions
For a car traveling 35 mph the distance required to brake for a stop is normally distributed with mean of 55 feet and standar deviation of 8 feet. You are traveling 35 mph in a residential area and a car moves abrupt into your path at a distance o..
explain the necessity of super elevation in the design of horizontal curve also prove that rv=v2/{g(fs+e)}
Liquid flows with a free surface around a bend. The liquid is inviscid and incompressible, and the flow is steady and irrotational. The velocity varied with the radius across the flow as V = 1/r m/s where r is in meters.

A 2 foot tall multi-stage weir placed in a channel to cause the water to flow over the contracted weir at a height of 0.75 feet. There are 2 contractions and the original length is 6 feet. What is the discharge, in cubic feet per second
According to a settlement analysis, the weight of this fill will cause 600 mm of the total settlement over a period of 30 years. The differential settlement will probably be about 100mm. Although the building could be supported on spread footing f..
As a design engineer you are responsible for all the drawing documentation from your organisation. What are the key aspects of the drawing you need to check before sending it to the construction division
A train starts from rest at station A and accelerates at 0.5m/s^2 for 60s. Afterwards it travels with a constant velocity for 25min. It then decelerates at 1 m/s^2 until it is brought to rest at station B.
