I want to calculate how much weight a PVC panel will support, for instance, If a person were to lie on top of the panel, what is the maximum weight of the person that this panel will support, before breaking. Its thickness is 1/4th inch. It has a length of 84.5 inches and a width of 12 inches. This panel is support in both of the shorter ends by an aluminum railing.

1. For a normal population with known variance s2, answer the following questions:

(a) What is the confidence level for the interval: ?− 1.85?/√?≤ ?≤ ?+ 1.85?/√??

(b) What is the confidence level for the interval: ?≤ ?+ 1.4?/√?

Determine the ultimate load carrying capacity of a group pile in the following scenarios: a) Piles are 20 m long, 3 by 3 in plan, square in cross section and to be driven into a granular soil b) Piles are 20 m long, 3 by 3 in plan, square in cross section and to be driven into saturated clay soil c) Provide a reflective comment on your results

A simply supported beam of length 7m has a concentrated couple M_o (counter clockwise) of 10kNm applied at one end.

Using DIM(Double Integration Method):

1. The maximum deflection is located at what distance from the applied load?
2. Calculate the maximum deflection assuming E = 200 GPa and I = 60x10^6 mm⁴

Design an isolated rectangular footing to support an interior column 40 cm × 40 cm in cross section and carries a dead load of 800 kN and a live load of 600 kN. Use f́c= 21 MPa, fy= 420 MPa, q all (net) =200 kN / m2 , γsoil = 17 kN /m3 , and Df =1.25 m. Space limitations are such that one lateral dimension cannot exceed 2.5 m

. Design a square footing for a 16-in. square interior column with an ultimate dead load = 300 (k) and an ultimate live load = 200 (k). Take f_y=60,000 psi, f_c=4000 psi, normal weight, and q_a= 4500 psf. Assume the base of the footing is 4 (ft.) below grade. Draw the reinforcement detail also. Check for one way and two way shears with the support of diagram. With ACI code

Use the following data to calculate the layout of an equal tangent vertical curve
by offsets for every full station.
g1 = -1.20%
g2 = +3.50%
X PVI = 49+70
Y PVI = 5,893.48’
L = 1500’
, find the station and
elevation of the high (or low) point of the curve.

Why are bearers and joists (like those in a suspended flooring system) always orientated so that the biggest cross section dimension is vertical?
