Homework Statement
James Gomer holding a uniform 40 N rod of length 1 m horizontally with a hinge on its left end and a vertical string on the right end. Now suppose a fully laden swallow with a mass of 2.00 kg lands and squawks loudly on the rod at a point 30.0 cm to the right of the hinge. Now what is the force exerted by the string to keep the rod horizontal?
Homework Equations
The Attempt at a Solution
I figured out that the string with no force exerted on the rod is 20N, so Far I have
Ʃfnet = 2kg*9.8*20(moment arm) - F*20
I don't think I have my setup correct though.. I'm just not visualizing this well
