Test specimen Hammer Charpy Impact test pendulums are used to determine the amount of energy during fracture (see ASTM E23). The hammer weighs 71.2 lbs and the arm weighs 19.5 lbs. I G about its own CG for the hammer is 20.9 slug-in 2 ; it is 47.1 slug-in 2 for the arm about its own CG. The pendulum is cocked in the position shown 39 o above the horizontal. What is the impact speed when the hammer hits the test specimen? IC23.2 – Charpy Impact Tester If the hammer continues its swing to 20 degrees below the horizontal, how much energy did the specimen absorb?

Unformatted text preview: What is the force on the pin O just before the hammer hits the specimen? Solution: Problem Type: Find: Given: The 15 kg bar passes position 1 with an angular velocity of 0.1 rad/s. The distance between A and C is 4 meters and the bar is 2 meters long. The spring constant is 50 N/m and in position 1 it is stretched 0.5 m. Find the angular velocity when the bar hits 60 degrees. IC23.2 – Swinging Rod and Spring Problem Type: Find: Given: C ,O...
