Therein lies the problem. I am being to ask to validate something where no work was shown and only the final result.

Lets neglect the floor stiffness for right now and assume its rigid and inelastic. L is an unknown that we are trying to solve. I actually already have an answer that someone else did and was asked to validate, but am having an issue replicating. This is an excerpt from the document i am trying...

Hello I am trying to setup a problem to represent a pipeline crossing over another perpendicular pipeline on the seabed. I am trying to represent the problem as a simple beam and having some issues with the supports i am selecting and the boundary conditions. Attached is a picture representing...

Homework Statement A plunger of mass m rests on a spring with constant k. The spring is pressed down a distance x and released from rest. How large does the the mass need to be in order to keep the plunger in contact with the spring? Homework Equations PEf+KEf=PEi kx-mg+N=0 The...

Aha! I forgot to distribute that minus sign! Here is what I get now and no longer have a 0 in denominator. Theta2 = arccos(1-((e+1)2*(m2)2*(1-cos(theta1)))/(m2+m1)2) Look better?

Ok let's see how this looks for a final answer Theta2 = arccos(1-((e+1)2*m22*(1-cos(theta1)))/(m2-m1)2) The only issue I see with this answer is that if m1 and m2 are identical, we then have a 0 in the denominator. I have worked it out twice and gotten the same answer both times, so I...

I have taken your suggestion and used the conservation of momentum equation to solve for v'1 and the resultant equation I get is: v'1=v1-(m2)/(m1)*v'2 plugging this into the coefficient of restitution equation along with the other solved variables leaves me with...

The problem is purely symbolic and since its not specified otherwise I assume that m1=m2. If that was the case then v'1 would be zero correct? I leave the coefficient of restitution in since the problem states that's it's a known. Besides those questions you had, does it look like I am on...

Homework Statement A pendulum of mass m_1 is released at an angle theta_1 and strikes the pendulum of mass m_2, which rises to angle theta_2. The coefficient of restitution e for the two masses is given. Derive an expression for the angle theta_2. Homework Equations KE_1+PE_1=KE_2+PE_2...
