For each problem, one curved surface is shown restraining a body of static fluid. Compute the magnitude of the horizontal component of the force and compute the vertical component of the force exerted by the fluid on that surface. Then compute the magnitude of the resultant force and its direction. Show the resultant force acting on the curved surface. In each case the surface of interest is a portion of a cylinder with the length of the surface given in the problem statement.Use Fig. 4.51. The surface is 4.00 m long.

consider a 1000-w iron whose base plate is made of 0.5-cm-thick aluminium alloy 2024-t6 p2771 kgm3 and cp 875 jkg c.
K characterizes heat transfer by natural convection from the exposed surface of the layer, esti- mate the time required to completely melt the frost. The frost may be assumed to have a mass density of 700 kg/m3 and a latent heat of fusion of 334 k..
In a cold winter day, wind blows over the wall of a house at 40 km/h. The outside air temperature is reported to be -7°C. The wall is 8 m long and 5 m height whose surface temperature is 10 °C.
Nan crystalline materials have grain sizes ranging from 0.01 to 0.1 microns. If the contribution of grain boundary strengthening in an alloy with grains of 0.1 microns is 20 MPa, what would you expect it to be if the grain size were reduced to 0.01 m..
determine the smaller of the two section moduli for the beam. (Recall that section modulus is equal to bending moment divided by maximum bending stress.) In which material does the maximum stress occur?
