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.
a quality of water within a piston-cylinder assembly executes a carnot power cycle. during isothermal expansion the
One mole of an ideal monoatomic gas initially at 300 K is expanded from an initial pressure of 10 atm to a final pressure of 1 atm. The molar heat capacity for constant volume for the gas is Cv = 3/2 R .
Adequately describe the abiotic factors that determinethe types and numbers of species found in yourzone. Examples of factors: temperature, access to sunlightfor photosynthesis, dissolved oxygen content, availability of nutrients such as carbon.
It rains 3.0 in. on a 20.0 acre watershed. What is the volume of rainfall excess if 30% of the watershed area is a lake and infiltration on the soil is estimated at 1.0 in? What is the total volume of runoff? Express your answer in cubic feet.
A 150 mm diameter by 300 mm long sample taken from the peat deposit was weighed and found to have a total mass of 5036 g and after oven-drying a dry mass of 387,4 g.
A bridge having a horizontal top cord is span between tow piers Aand B having an arbitrary height. It is required that apin-connected truss be used, consisting of steel members boltedtogether to steel gusset plates. The end supports are assumed to be..
Evaluate the pressure head at point a and determine the vertical effective stress at point b and evaluate the lateral pressurein the brown clay
If an analysis is made of the hydraulic conductivity of a site using permeameter tests of core samples, slug tests of monitoring wells, and pumping tests of production wells, it is often observed that the hydraulic conductivity as measured by each..
The modulus of elasticity of an un-identified metal is known to be 3000 ksi. An engineer has to design a rod with a fixed diameter to carry a load, P, and wishes to keep the deformations in the rod to a minimum.
This unit enables learners to develop an understanding of the methods and techniques used to create civil engineering structures and the skills needed to solve problems associated with civil engineering activities
