A present sum of $50,000 at an interest rate of 12% per year compounded quarterly is equivalant to how much money 8 years ago
the pin at B is attached to member ABC and can slide freely along the slot cut in the fixed plate. Neglecting the effect of friction, determine the couple M required to hold the system in equilibrium when.
A 1.5 m diameter culver (concrete barrel, well - rounded entrance) that is 20m long is installed on a slope of 2 percent. The design discharge is 9.5 m^3/sec and the inlet will be submerged but not the outlet.
The truss is to be constructed of members with equal cross-sectional areas and using a material with yield stress 700 MPa. The structure must be designed to support a mass (m) of 3400 kg with a factor of safety of 3.
A $78,000 invtestment in machinery is proposed. It is anticipated that this investment will cause a reduction in net annual operating disbursements fo $16,300 a year for 12 years. The investement will be depreciated for income tax purposes
A catchment has an area of 150 ha and a runo/rainfall ratio of 0.40. If due to a 10 cm rainfall over the catchment a stream flow at the catchment outlet lasts for 10 hr, what is the average stream flow in the period
A worker needs to enter a confined space to tighten the packing on a leaking argon valve. Describe two procedures that could be used to isolate the argon line and valve prior to starting work.
Also, at the failure cross sections the diameters are found to be 0.731 in., 0.645 in., and 0.587 in., respectively. Determine the percent elongation and percent reduction in area of each specimen.
The Washington Monument is 169 m tall. What is the stress in the lowermost rock if it is made of Georgia granite?
two isotropically consolidated undrained (ciu) triaxial tests, CU1 triaxial tests, CU1 and CU2, were conducted on a normally consolidated (Nc) clay under effective consolidation stresses of 100 and 200 kPa respectively.
Force F with magnitude indicated acts at point o. determine the magnitudes of the components Faa and Fbb along directions a-a and b-b so that F=Faa+Fbb
Determine the major and minor principal stresses at failure and the effective stress friction angle (assume c' = 0). Plot the Mohr diagram.
Imagine a virtual expressway having 3 lanes. The administrating agency wants to detect traffic accidents in 5 minutes wherever they occur to dispatch an emergency response unit.
