Homework Statement
To prove that system will travel freely upto 180 degree
m2 is counterweight and m1 is mass of pan (=3kg)
i have attched the fbd or another link http://www.imagebam.com/image/54bb5a394377595
Homework Equations
m1(h + a sin θ) g x = m2 y h g
m2 = 9.13 kg
The Attempt at a Solution
we are stuck at the following equation
Pwg ≥( m1 x^2 + m2 y^2) sin2 θ / [ x(h-xsin2 θ)]
LHS is weight of pan and arm and if LHS>RHS, system will rotate freely
is this correct? can you pls explain it properly because it will clear my concepts.
Thanks.
