No worries! What extra slope were you referring to?The radius where F_cam peak is?

The goal is to properly re-define the spring rate; they are currently incorrect and failing the test. I suppose I wanted to brush up on my rusty physics too, and to have an analytical method for verification. COS 44 = F_s / 51.9, no? On a side note, is this a similar problem to a wheel going...

I am a little lost on that radial force. Here is a better view of the spring - roller system, both springs and roller are connected by a pin, the spring sits on a guide. The roller moves the pin, and the pin carries the guide which compresses the springs.

Yes, the roller is free to roll, and is constrained to move only along spring axis. I think I now understand why that 'r' is irrelevant, even though the force is applied at the handle of the torque meter, it is then transmitted through the whole torque meter + extension + cam system, treating...

My bad, the diagram is misleading, the roller and the spring are constrained to only move up and down as it's pushed by the U-shape cam. The two positions are relative to the cam only.

A torque meter with a triangular slab extension is inserted into a corresponding triangular slot. The C-shaped arm features a V-shaped dent on which a roller is seated. This roller is held in compression by a spring. The roller's positions are labeled '0' for the initial state and '1' for the...

Thank you! yeah it's from my professor's power point, I think power points are prone to typos..I should have known better

Homework Statement [/B] Given a group of 100 married couples, let X1 be the number of sons and X2 the number of daughters the couple has. P(X1 = 0, X2 = 2) = f(0, 2) = 8 /100 = 0.08 2. Homework Equations The Attempt at a Solution I tried to look for a similar example online, I found this...
