A trough whose cross section is a trapezoid is b = 8 m across at the bottom, a = 12 m across at the top, and 4 m deep. If the trough is filled to 1 m with water, what is the force due to water pressure on one end of the trough? F a C (Hint: Using SI units, pg = 9800 N/m³.) (Use decimal notation. Give your answer to two decimal places.) Incorrect b 55533.33 N

Fluid Force. A swimming pool is filled with fresh water to a depth of 7 feet measured at the deep end. There is not enough water in the pool to reach the shallow end. Assume that the pool is constucted using right angles, except where the bottom of the pool meets the end walls. Use Ah for the height of a typical strip across the face of the wall. 6.

b)A simply supported beam has a symmetrical rectangular cross-section. If the second moment of area (I) of a beam with a rectangular cross-section is 11.50 x 106 mm4 about its centroidal x-axis and the depth dimension (d) of the rectangular section is 180 mm, determine the breadth dimension (b) for this beam section. Give your answer in millimetres (mm) and to 2 decimal places. Assume the beam section material is homogeneous c) The same rectangular cross-section beam in Q2b is subjected to a maximum bending moment of 25,000 Nm and experiences sagging. Assuming that the centroidal axis passes through the beam section at (d/2), calculate the maximum bending stress (?max) the beam will experience. Give your answer in N/mm2 and to 2 decimal places.

Question 6 A weir is a barrier that spans across the width of a river and is used to alter its flow characteristics. Typically, this results in a change in the height of the river level. The figure below shows the cross-section of a broad- crested weir. The symbols in the figure are Hw – the height of the weir (m), Hà – the head above the weir (m), and H = Hw + HA – the depth of the river upstream of the weir. The flow across the weir (Qw) (m'/s) can be computed using the following expression: 3/2 3/2 Qu = CuBug ) H Hw Weir 3 Bw where Cw is a weir coefficient (dimensionless), Bw is the weir width (m), and g is the gravitational constant, taken as 9.81m/s'. The weir coefficient can be determined using the weir height (Hw): 1+ H/H 2+ H/Hw Cu = 1.125. In this problem, assume: g = 9.81m/s", Hw = 0.8 m, Bw = 8 m, and Qw = 1.3 m/s. Complete the following: (a) Determine the upstream depth (H = Hw + Hà) using simple fixed-point iteration with an initial guess of Hi=0.5Hw. Complete two…
