Determine the largest screw spacing for the pi-shaped beams that allows the beams to carry an ultimate shear load of V = 2000 lbs. Each screw can support 350 lbs.
Determine the required shear strength (psi) for the wood to ensure that it is 2 times stronger than it needs to be.
Starting from x = 0 with no initial velocity, the acceleration of a race car is defined by the relation a = 6.8e-0.00057x, where a and x are expressed in m/s2 and meters, respectively. Determine the position of the race car when v = 30 m/s.
If a mechanical device requires 450J of work to do 310J of work in lifting what is the efficiency of the device?
A 301 stainless steel wire is suspended vertically from itsend. The wire is 400 ft long, diameter .75 inches, specific weight= 489 lb/ cubic foot.
A froth flotation process is used to concentrate copper ore. It is a two stage process with a rougher stage followed by a cleaner stage. The cleaner tailings are returned to the rougher flotation.
while groundwater andinfiltration losses over the period were estimated to be 0.6 inches. Determine the combined amounts of water evaporated and transpired from the region during the year of record.
A steel tank with 2.5 m high vertical walls and a flat triangular floor is filled with three immiscible liquids layered upon each other. Two of the walls are 1.2 m long and perpendicular to each other.
In an undisturbed soil formation, it is known that the dry soil weight is 115pcf. The specific gravity of the soil particle is 2.75.a) What is the saturation wet unit weight of the soilb) What is the submerged weight of the soil?

Water pressurized to 3.5 x 105 Pa is flowing at 5.0 m/s in a pipe which contracts to 1/3 its former area. What is the pressure and velocity of the water after the contraction
Air enters a turbine operating at steady state at 8 bar, 1127 C and exits at 1.5 bar, 347 C. The heat transfer from the turbine to its surroundings is 10 kJ/kg of air flowing through the turbine. Neglecting kinetic and potential energy changes and as..
A soil sample was taken from a proposed cut area in a highway construction project and sent to a soils laboratory for a compaction test, using the Standard Proctor compaction procedure. Results of the test are as follows:
A borehole at a site reveals a soil profile comprising 6 m deep fine sand layer overlying a 9 m thick clay layer, which in turn overlies weathered bedrock. The groundwater table is located at a depth of 4 m from the ground surface.
