For a 30ft simply supported beam, there is a uniform load of 1.5 k/ft. along the length and two point loads of 20 kips each spaced at (from x=0 to x=30ft left to right) x=10ft and x= 20 ft. How do I find the maximum moment for the beam? (preferably using simple equations if possible)
The design parameters are: • Q = 65 m3/d, • Wetland area (A) = 0.23 hectares (2,300 m2) (including the safety factor), • Aspect ratio = 8:1 • Average water depth (d) = 0.5 m • Bed slope = 1% (0.01 m/m) Given that the Manning's resistance factor
A 58.3 degree inclined plan has a spring with spring constant 23,400 N/m attached at the bottom.A 1.2 kg block is placed on the plane and compresses the spring a distance of 2.4 cm from equilibrium.
