1. The problem statement, all variables and given/known data The trebuchet is a siege engine that was employed in the Middle Ages to smash castle walls or to lob projectiles over them. A simpliﬁed version of a trebuchet is shown in the following ﬁgure. A heavy weight of mass M falls under gravity, and thereby lifts a lighter weight of mass m. The motion of the mass M is blocked as shown in the ﬁgure, which launches the lighter mass m; the blockade forms an angle θ with the vertical. The mass of the blockade is much larger than all other masses. The shorter arm of the trebuchet is of length H , whereas the longer arm is of length l; the whole beam (both arms) are of mass µ. 2. Relevant equations conservation of energy 3. The attempt at a solution ok i did the solution but i got a super complicated expression for omega i will is it supposed to be that way? and is it possible to get a numerical value for omega from the given information? i have just described my solution in words if you want my actual equations i would gladly post thanks x y a b are heights above ground I moment of inertia v translational velocity of masses Ei = Ef Mgx + μ(L+H)gy = Mga + μ(L+H)gb + 1/2 I ω2 + 1/2 Mv2 + 1/2 m v2 y = (L+H)/2 sin tan-1(H/L) x = (L+H) sin tan-1(H/L) a = H(1 - cosθ) b = H + (L-H)/2 cosθ I = 1/12 μ(L+H)3 + μ(L+H)(L-H)2/4 v of M : ω* H v of m : ω * L is this correct?
