A boy stands on a diving board and throws a stone into a swimming pool. The stone is thrown from a height of 2.8 m above the water surface with a velocity of 7.37 m/s at an angle of 60.0° above the horizontal. Determine the horizontal distance the stone travels before it strikes the water. Answer: Check
A boy stands on a diving board and throws a stone into a swimming pool. The stone is thrown from a height of 3.67 m above the water surface with a velocity of 5.35 m/s at an angle of 60.0° above the horizontal. Determine the horizontal distance the stone travels before it strikes the water. Answer: Check
A boy stands on a diving board and tosses a stone into a swimming pool. The stone is thrown from a height of 2.50 m above the water surface with a velocity of 4.00 m/s at an angle of 60.0° above the horizontal. As the stone strikes the water surface, it immediately slows down to exactly half the speed it had when it struck the water and maintains that speed while in the water. After the stone enters the water,...
Problem 3: Consider the situation in the figure - a student diver in a pool and an instructor on the edge, outside the water. Since the indices of refraction of air and water are different, the light rays coming from the diver and the instructor are refracted at the surface, changing their apparent position with respect to each other. The diver sees the instructor at an apparent angle of θa = 26°, measured from the normal to the interface. Randomized Variables: θa...
Problem 2 (30 points): Bored at the swimming pool and without enough solid mechanics to occupy their minds over the summer, engineering students analyze a diving board made from a 50mm x 300 mm wood plank. The diving board is held down at end A by anchor bolts that can be considered as a pinned support. a) Draw the Shear and bending moment diagram for the beam (10 points) b) What maximum permissible load, Pmax, can be exerted on the...
A flashlight is held at the edge of a swimming pool at a height h = 2.2 m such that its beam makes an angle of θ = 58 degrees with respect to the water's surface. The pool is d = 1.5 m deep and the index of refraction for air and water are n1=1 and n2 = 1.33, respectively. What is the horizontal distance D, from the edge of the pool to the port on the bottom of the pool...
(20%) Problem 2: A flashlight is held at the edge of a swimming pool at a height h = 2.4 m such that its beam makes an angle of θ 41 degrees with respect to the water's surface. The pool is d = 2.25 m deep and the index of refraction for air and water are n1 = 1 and n2-1.33, respectively Randomized Variables h 2.4 m d 2.25 m 6% 41 degrees What is the horizontal distance, D, from...
(8%) Problem 3: Consider the situation in the figure -a student diver in a pool and an instructor on the edge, outside the water. Since the indices of refraction of air and water are different, the light rays coming from the diver and the instructor are refracted at the surface, changing their apparent position with respect to each other. The diver sees the instructor at an apparent angle of e, - 33", measured from the normal to the interface Randomized...

Problem 4 (30 pts): Deflection A diving board is simply supported with an overhang portion from C to B. A diver standing at the free end B has weight W = 205 lb. Assume the diving board has constant properties El with length L = 8 ft and E = 10,000 ksi. Use these bending moment equations to answer the questions below: M(x) = -2Wx, (0 < x < 1/3) M2(x) = Wx-WL , (L/ 3XL) W y EI A...
