how can i find the the volume of the water and height of the wetted part of the inverted cone inscribing a sphere given its radius?

if the eye is at a point under water, what is the greatest angle measured from the vertical line that a star can appear to be?

When buckling a plate of two ends fixed, the deflection equation of the plate can be expressed by: y=y0*(1-cos mx) where the maximum deflection at the center is 2*y0. With this equation, the cross sectional area and the young's modulus of the plate is usually unchange.

1)An excavation is 12 ft. deep and has trapezoidal sides (faces). The upper base is horizontal rectangle 400 ft. by 180 ft., and the lower base is a horizontal rectangle 350 ft. by 150 ft. How many cubic yards of earth were removed in digging the excavation?

Problem: A frame consists of two bars joined rigidly at B and built in
at A and C (see Figure). Determine the bending moment M at B
and the compressive force P in AB when, due to a rise in temperature,
the bar AB increases in length by

Answer. P and M can be found from the equations:

Hello.. and good evening.

I would like to know how to solve for the area of the mid-section of this prismatoid. I tried solving for the volume and I got an answer of 375 cu. ft. but according to Kern and Bland's book the real answer is 310 cu.ft. I guess I made a mistake in solving it.

Can I know the complete solution and the illustration of the top view of the prismatoid's mid-section? Thank you very much to whoever will answer my question. It would be a great help for me.

a car if nass 1600kg coast down a 10 percent grade from A to B, a distance of 30m and then coast along a level road until it stops at C. assume the road resistance to remain constant of 200N for the entire distance A to C, if the initial velocity of the car at A is 25kph, compute:

a.) its velocity at B
b.) the distance s it coast from B to C.
