Determine the influence line ordinates for R1 for the two-span pin-jointed truss shown in Figure S5.4as unit load crosses the bottom chord. All members have the same cross-sectional area, modulus of elasticity, and length.
If a mortar is proportioned to 0.11 ft3 of cement, 0,03 ft3 of lime, 0.27 ft3 of water, and 0.50 ft3 of sand, the percent voids in the sand is? (Assume a sand Bulk Specific Gravity Oven-dry of 2.60; of cement 3.15, and lime 2.25 if needed).
The city of Lancaster's water distribution system has 3 wells for water supply. There are 10 pumps at these wells. It is estimated that a pumping rate of 10,000 gallons per minute is needed to satisfy the city's total water demand.
The L bracket shown below is pinned to the ground at point C and attached to a single cable at points A and D that wraps around a frictionless pulley at point B. Determine the forces acting on the bracket at point C and then tension in the cable.
each report may cover all items included in the description of the project below1. toxic and hazardous waste how are
Assume the following equations for the total benefit and totalcost of a reservoir project as afunction of scale, Q, expressed asmillion gallons water delivered per day(MGD):
how much money today is equivalent to lump sum of $100,000 in 20 years with interest rate of 6% per year compounded (a)monthly, (b)quarterly, (c)semiannually
A 2-kg block slides on the smooth circular path (Quadrant One of full circle, block moving left to right). If it is released from rest when theta=0 degrees, determine the force it exerts on the path when it arrives at Point A
Alexis borrows $10,000 today and promises to pay it back in equal monthly installments of $250. If the agreed loan interest rate is 6% compounded monthly
Determine the allowable moment about the horizontal neutral axis that a timber beam with nominal size 50 X 100 can resist without exceeding the allowable stress of 10 MPa. The dressed size is 38.1 X 88.9 mm, I = 0.00000223m^4, and S = 0.0000502 m^3.
Determine the acceleration of the initially stationary 20-kg body when the 50-N force P is applied. The small wheels at B are ideal, and the feet at A are small.
Structure O A B C is built in at point O and supports forces from two cables. Cable E A D passes through a frictionless ring at point A, and cable O C G passes through a frictionless ring at point C. If the force in cable E A D is 800 lb and the forc..
Would it be more efficient to use the method of section on the diagonal cross member part of the truss or do you have to use the method of joints to determine other forces first?
