I got sloppy with the paint tool. Sorry. It was supposed to be I.C. , the acronym for instantaneous center.
Okay next fundamental question, there are 3 additional forces acting on the particle. The friction force, force due to bank angle and the normal force due to gravity.
1) Is the force...
First of all. Thanks for your help. I clearly am having a physics fundamental issue here. I have a fundamental question before I rehash the scenario here.Centripetal force is sucking the car in towards the instantaneous center of rotation right?
Homework Statement
A car traveling 10 m/s is moving along a track banked at 5 degrees. The tire-road friction coefficient is .3 What is the minimum radius it can travel without slipping?
v0= 10 m/s
Bank Angle Θ = 5°
μ=0.3
Note I am working through prep material for the exam. The solution...

This thread shows how to combine equivalent spring constants in different arrangements. I was adding them all in parallel. I see my mistake now. Thanks Chet, I'll keep the questions coming.
Homework Statement Problem: [/B]
Given the mass spring system solve for k1
The natural frequency wn = 10 s-1
k1=2k2
m=1kg
Homework Equations
wn=(k/m).5
The Attempt at a Solution
solve for k1
m x w2n =2.5k1
k1 = 40 N/mNote: I calculate 40 N/m and the solution states 250 N/m. I think I...

what is the instantaneous center of rotation for the rigid body.
OA = 16
AB = 25
AD = 60
BC = 35
ωOA=2s-1

Ya I messed that up. I will begin at the node with 2i going in and i going out. It seems that I overlooked this situation. If 2 i is going in and i is going out then the 3 ohm resistor must have 1i going into that to have a KCL law satisfied.
