The Banner Hammer

Designed and constructed by:Mark Boudreau, Alex Cox, Nick

Guernsey, Jake Henke

Step 1: the domino effect

•The force applied to the block of wood creates torque.•The torque creates rotational motion.•The rotational motion is transferred between the blocks

Step 2: getting the ball rolling

•The rotational energy of the block is converted into rotation and linear energy in the ball.

Step 3: the setup

•The force of the ball creates tension in the string pulling the hammer up

Step 4: hammer time

•The potential energy of the hammer is transferred to kinetic energy in the tennis ball

Step 5: the seesaw

•The platform pivots with the weight of the ball

Step 6: the wrecking ball

•A string holding the banner is under the blocks•The kinetic energy of the ball knocks over the blocks releasing the string and the banner

Tadaa!!

Construction Problems

• The ball wouldn’t fall from the cup

• The vibrations from the ball falling would shake the string loose from the blocks and display the banner prematurely

• The first block of wood wouldn’t balance with the ruler taped to it

Conclusions

• Anything that can go wrong will

• Theoretical physics doesn’t translate to real life

• Don’t listen to Jake EVER
