Problem 2.16 [2.21] Get the equations in terms of theta and using symbols,m,k, l,l 1 ,l 2, and F(t) Please use theta as positive for F(t) positive as shown note: the bar ( or beam ) is zero mass in this case. Modify Problem 2.17 [2.22] 1) Derive the equations in terms noted plus M b . Icg b The now massive rigid bar or beam has a length of l + l 1 2) Now put in numbers and design the damper as stated. 3) Find amplitude of steady state theta response as stated. 4) What is the steady state amplitude of horizontal motion of the tip mass, yes, x = l times theta.
