1.How do you calculate the modulus of resilience and toughness from a graph and get a numerical value? Is there an equation? If so what is it?
2.Find the maximum deflection of a wooden bearer which has three supports; one at each edge (2) and one in the middle (2m from each other). Bearer holds a UDL over its whole length (4m) of 600 N/m.
Data:
bearer: 0.045x0.12x4 (rectangular)
E=14000 MPa
3.Two chambers, A and B both have manometers with the same fluid with specific gravity 1.4. When h(sub a) = 6 cm and h(sub b) = 4 cm, what is the gage pressure in chamber A?
A clean glass capillary tube having a diameter of .008 in. was inserted into water with a surface tension of 0.00504 lb/ft. Calculate the height of the capillary rise in the tube.
When loaded, the beam carries a 10-kN/m uniformly distributed load. Neglecting the weight of the cable, approximate the following: (a) The change in length of the cable when the beam is under load
The flow is designed using a rectangular coordinate system whose orgin is at the free surface midway between the walls. The x axis is normal to the walls, and the y axis points vertically downward.
If the elevation of the pipeline at the treatment plant is 125 m, estimate the pressure in the pipeline 1 km downstream where the elevation if 110 m. Hint: Use the Colebrook equation to estimate f, and the energy equation to estimate P2 .
