So I have a simple lever that is connected to an extension spring. When the extension spring is exteneded it applies a force of 40lbs on the lever. The lever is 3 feet long and the pivot point is 1 foot from the top and 2 foot from the bottom. The lever weighs 2.1 lbs and has a 3lb weight...

sorry So I have a spring being extended at the top with a force of 51765 lbf being applied to the arm. The arm weighs approximately 2.1 lbs and is 3 feet long. The pivot point is 1 foot from the top and 2 feet at the bottom. Can anyone help me find the final velocity at the bottom point in...

I have to find the speed that the end of the arm goes. Can anyone help i attached a diagram

Homework Statement Integral of (3x+2)/x(x+2)^2+16x Homework Equations The Attempt at a Solution That breaks down to A/x + Bx+c/x^2+4x+20 so 3x+2 = Ax^2+4x+20 + Bx^2 + Cx then I found the values of A b and C then I can't figure out what to do please help

Homework Statement Integral of sqrt(x-1)/sqrt(x) Homework Equations The Attempt at a Solution I think I have to sub x = sinh2 so you get sqrt(1-sinh2)/sqrt(sinh2) I forget what to do after this

well you see there bob I am not too sure how to get started and what to do with the ln
