1. The problem statement, all variables and given/known data In an Effort to tighten a bolt, a force F is applied to the end of a wrench that has a length L perpendicular to the wrench. If the bolt itself has a radius of b, how much force is applied to the bolt 2. Relevant equations ∑τ=RFsinθ ΣF=ma ∑T=Iα 3. The attempt at a solution I tried summing the torques ∑τ=LF+bF=(I_bolt+I_wrench)α but the answer choices are a)F b)Fb/L c)FL/b d)FL/(b+L) e)bL/F I'm not even sure how you would solve this to get anything like that or why there is an F in the answer when we're solving for F. My friend says this is a conceptual engineering problems and that c makes sense since the Force is multiplied by the length of the bolt (they are really looking for torque) but divided by the length of the wrench.
