4ft Locate the center of gravity along the y-axis of the homogeneous "bell-shaped" volume formed by revolving the shaded area about the y axis.

Determine the deflection at point B for the beam shown by the moment-area method.

As shown, a round viewing window of diameter D = 0.8 m is situated in a large tank of seawater(S = 1.03). The top of the window is 1.2 m below the water surface, and the window is angled at 60° withrespect to the horizontal. Find the hydrostatic force acting on the window and locate the corresponding CP.

2. A uniform rectangular block is attached to a cart that is accelerating up a 20° incline at 3 m/s². The block is attached to a cart by a hinge at Point A and a roller at Point B. a. What is the force that the roller is applying to the block at Point B? b. What is the force that the hinge is applying to the block at Point A? Y a = 3 m/s² х 20° 0.8 m m= 100 kg B 0.6 m 1.0 m g
