1.Why is the anchorage capacity of a standard hook not increased by extending the bar well beyond the end of the hook?
2.Two solid cylindrical rods are joined at B and loaded as shown rod AB is made of steel(E=200 GPa) and rod BC of brass ( E = 105GPa) determine a) the total deformation of composite rod ABC, b) the deflection of point B.
3.What is the conclusion of T-Beam?what is the main point we should know about T-Beam?How to make the project of T-Beam become strengh?
4.Water is to be pumped along a 150mm diameter asphalted cast iron pipe at a rate of 0.9m3 /min. The pipe is 3 km long and rises 26m in this length. Calculate the frictionalhead loss, and the shear stress on the pipe wall. What power of pump will be requiredto maintain the flow? Use a Moody chart.
The joists from the previousquestion are supported by concrete beams that are 300mm wide by 500mm deep. The concretebeams span 8.4m. Assume the beam is also simply supported. The weight of the joistis 1.04 KN/m.

A dispersed plug chemical reactor has an influent flow with concentration of 150 mg/L of A and a flow rate of 100 gal/min (380 L/min). The reaction is first order, The rate equation : - dC/dt = kC= -r , and the rate constant is 0.4 h^-1 .
Consider a 2D triangular element with the three vertices at 1[1,1], 2[1,2] and 3[2,2]. the displacements at these t hree points are [0.1,0.1], [0.3,0.2] and [0.4, 0.3] mm for point 1,2,and 3 respectively
Near the point (x, z) =(3,2) in a flow with a zero y-component (v=0), the velocity component are described by u =3x-3z, and w = 6-4z+ x. The velocities u and w are in m/s and are in the x- and z- directions, respectively.
Using Rate of Return Analysis, determine the most economical alternative below. Assume a minimum attractive rate of return of 6%, and a 5-year life with no salvage value for each. The alternatives are mutually exclusive
Water is flowing in a trapezoidal channel with 10 ft bottom width and 2H/IV side slopes. The channel is running on a slope of 0.00778 ft/ft and the flow exerts a shear stress of 1.5 lbs/ft2 on the channel bed. What is the depth of flow in this cas..
A 2.5hr long uniform rainfall resulted in arunoff hydrograph that has the shape of an equilateral triangle.The base of the triangle is 64hr; the peak flow is 535cfs; thedrainage area is 5.7mi^2. Determine the corresponding unithydrograph if the base ..
