A Sledgehammer Having A Weight Of 1000 N Strikes An Anvil With A Velocity Of 25 M S The Anvil Of A Forging Hammer Weigh 1 (110.23 KiB) Viewed 38 times

A sledgehammer having a weight of 1000 N strikes an anvil with a velocity of 25 m/s. The anvil of a forging hammer weighs 5000 N and is mounted on a foundation that has a stiffness of 50 kN/m. It is known that the amplitude of the resulting vibratory motion of the anvil is reduced by 80% in 5 cycles. a. Find an expression for the resulting motion of the anvil (x1(t)), if the hammer remains in contact with the anvil after the initial impact. b. Plot the response, xi(t) from 0 to 8 sec. c. Find an expression for the resulting motion of the anvil (xz(t)), if the hammer does not remain in contact with the anvil after the initial impact. (The kinetic energy lost due to impact is 35%.) d. Plot the response, xz(t) from 0 to 8 sec. Hammer W Anvil M x(t) gk
