Rotational mechanics

  1. Nov 23, 2013 #1
    1. The problem statement, all variables and given/known data

    A plank having mass 3.7 kg rides on top of two identical solid cylindrical rollers each having radius 5.5 cm and mass 2.9 kg. The plank is pulled by a constant horizontal force of 6 N applied to its end and perpendicular to the axes of the cylinders(which are parallel). The cylinders roll without slipping on a flat surface. There is also no slipping between the cylinders and the plank.

    1.) Find the acceleration(linear) of the plank(m/s^2).

    2.) Find the frictional force acting acting on the plank(N).

    M=3.7 kg
    m=2.9 kg
    r=.055 m
    F=6 N
    α = angular acceleration
    a=linear acceleration


    2. Relevant equations

    τ=Fr
    Ʃτ=Iα
    F=ma
    Frictional force(static) = force applied

    Hello, alleyferrell. Welcome to PF!

    As stated in the rules of the forum, you'll need to fill out part 3 ("Attempt at a solution") before any help can be given. So, show us what you've got so far.
