The bracket is subjected to the force of 3 kip. Determine the principal stress and maximum in-plane shear stress at point A on the cross section at section a-a . Specify the orientation of this state of stress and show the results on elements.
The volume and the average density of an irregularly shaped body are to be determined by using a spring scale. The body weighs 7200 N in air and 4790N in water. Determine the volume and density of the body. State your assumptions.
Draw the influence line for the shear at point B. Plot numerical values every 5 ft. Assume the support at A is a roller and C is fixed. EI is constant.
Two wooden members joined by a simple scarf splice and its diagram. The maximum allowable tensile stress in the splice is 75 psi. Determine the largest load P that can be supported and the corresponding shearing stress in the splice.
Explain how to utilize the graduated pendulum to measure the speed of a vehicle traveling in a horizontal circular arc of known radius r.

The gases are expanded to 140 kPa with a reversible adiabatic process. Calculate the work done by the gases, assuming they can be approximated by air with constant specific heats.
a 150 kg mass is suspended by wires from two hooks. the lengths of the wires have been adjusted so that the wires are each 50º from horizontal. assume that the mass of the wires is negligible.
A 2500-lb automobile is moving at a speed of 60 mi/h when the brakes are fully applied, causing all four wheels to skid. Determine the time required to stop the automobile (a) on dry payment (u=0.75), (b) on an icy road(u=0.10).
For load combination 1.2D + 1.6L, determine the maximum negative moment in each span and maximum negative moment at each support. remember that live loads shall be placed so as to cause the greatest effect.
If the forest is considered to be negatively affected at levels exceeding 300 ?g m-3, use your knowledge of atmospheric transport to determine whether the environmentalists' case is justified.
Plot the mass flow parameter m. 0(AP0) versus the Mach number for k =1.2, 1.4, and 1.6 in the range of 0 ≤ Ma ≤ 1.
