Question

My class is doing a robotics assignment and i have to write a paragraph explaining how my catapult meets the needs of my research field. my research field is past present future.

Answer 1

Both catapults and ballistas work by storing tension either in twisted ropes or in a flexed piece of wood (in the same way an archery bow does, but on a larger scale). A trebuchet tends to be easier to build because it consists simply of a pivoting beam and a counterweight that rotates the beam through an arc.
