To use free-body diagrams to determine internal axial forces and to learn how to calculate axial normal stresses. When a theoretical cutting plane is passed through an axially loaded prismatic bar, perpendicular to the longitudinal axis of the bar, and one side is analyzed as a free-body diagram, there is a uniformly distributed force acting on the bar's cross section. This uniform force distribution represents the action of the part of the bar removed on the part remaining and must exist to maintain equilibrium. The force distribution is an intensity of the force, or the force per unit area at the cross section, called the normal stress. Is is "normal" because it acts perpendicular to the section and it is a "stress" because it is an intensity of force distributed over a section (or area).The axially loaded bar is fixed at A and loaded as shown. Draw a free-body diagram and determine the support reaction at A. On paper, draw a free-body diagram of the bar and determine the reaction at A for the bar to be in equilibrium. Assume that the unknown reaction at A acts in the negative x direction.
How do you propose to do this at the above treatment plant and estimate the head loss both immediately after backwash and 10 hours later, if the same water is applied at a rate of 2 L/s.m 2 .
Determine the unfactored dead load and live load on a typical interior roof beam, sketch the loading on the beam, and draw the shear and moment diagrams for the beam assuming the beam is simply-supported.
A concrete box girder bridge has the rectangular x-section. The box is prismatic and considered thin-walled. It span is L=48m and simply supported at points A,B,C and D. The supports are assume to be able to transfer tensile forces.

Do the administrators of server systems still have to be concerned about, and take further countermeasures against DoS attacks, if so, what types of attacks can still occur, and what measures can be taken to reduce their impact?
An overpass is being built over the PVI of an existing equal tangent sag curve. The sag curve has a 70 mi/h design speed, and G1 = -6%, G2 = +3%.
Identical bricks 0.1m wide, and weighting 2kg are placed on a plate (assume the plate has neligible weight). Calculate the total weight (and force F required to balance the plate). How far from x=0 should F be placed so that the plate will not tip..
