Teeter Totter
A rocker arm has a length L = 3.2 m and mass M = 60.0 kg. Children of the mass m1 = 20.0 kg and 31.0 kg m2 = t sit on?
A seesaw has a length L = 3.2 m and mass M = 60.0 kg. Children of the mass m1 = 20.0 kg and 31.0 kg m2 = sit at both ends of the rocker. What is the m1 r1 distance of the child you must put the fulcrum so that the seesaw is balanced? best answer will be rewarded
Suppose that x = r1 and r2 = y. Y + x = 3.2. The value of R1 (M1) should be equal to r2 (m2). Therefore, x (20) y = (31) = 31 and 20x. You can then use the mathematical form to do so. x + y = 3.2 x = 3.2 and ….- 1 20x = 31 and 20 (3.2-y) = 31 and 64-20y = 31 20y = 33 y = 1.65 So = 3.2-r1 1.65 = 1.55 m Hope this helps.:)
