The pins on the frame at B and C each have a diameter of 0.25 in. If these pins are subjected to double shear, determine the average shear stress in each pin.
The design of a masonry wall to support vertical compression loading is influenced by the same factors that affect the design of all compression elements. One of these factors is the extent of rotational restraint at the top of the wall.
Assuming the origin is placed where the bullet begins to move, the force (in newtons) exerted by the expanding gas on the bullet is 18000 + 7000x - 20000x2, where x is in meters.
Maintenance expenses for a bridge in Georgia are estimated to be $200,000 for the first eight years followed by two separate million dollar expenditures in years 12 and 18. The expected life of the bridge is thirty years.

A 1 cm diameter, 0.4 m long steel rod is to be used in an application where it will be subjected to an axial tensile force of 15kN. The factor of safety based on yield stress must be at least 1.5, and the axial deformation must not exceed 2 cm.
A wide flange steel beam supports a permanent concrete masonry wall, floor slab; architectural finishes mechanical and electrical systems. Determine the dead uniform load in kips per linear foot acting on the beam.
The 1-hr UH in the table was recorded for a particular watershed. Determine the size of the watershed in acres and then convert the 1-hr UH into a 3-hr UH for the watershed.
Replace the given forces by a wrench and determine the coordinates of the intersection of its line of action (the coordinate of point P) with the plate. With a Force Fca=(100i+100j)N coming off of point C
A 3400-lb car is traveling in third gear (ratio 2.5 to 1) on a level road at its top speed of 130 mi/h. The air density is 0.00206 slugs/cuft. The car has frontal area of 19.8 sqft, a drag coefficient of 0.28, a wheel radius of 12.6 inches, a driv..
A water supply system is being designed to serve a population of 200,000 people with an average per-capita demand of 600L/Person-day (peak demand factor is 1.8) and a needed fire flow of 28,000 L/min.
