The point of maximum deflection δy occurs at the center of the specimen and is described by δy=fl348ei (12.11) where e is the modulus of elasticity and i is the cross-sectional moment of inertia. what is the value of i for this specimen?

What is created when solids,liquids,an gases mix with one another

Aball is thrown from the top of a building with an initial velocity of 21.9 m/s straight upward, at an initial height of 51.6 m above the ground. the ball just misses the edge of the roof on its way down, as shown in the figure. (a) determine the time needed for the ball to reach its maximum height. (b) determine the maximum height. (c) determine the time needed for the ball to return to the height from which it was thrown, and the velocity of the ball at that instant. (d) determine the time needed for the ball to reach the ground. (e) determine the velocity and position of the ball at t = 5.35 s.
