The figure provided with the question is:
I set up the following equation for path 4
##U_{path 4}=U_{Fk1, path 4}+U_{Fk2, path 4}+U_{FIK, path 4}## where ##U_{FIK,AB}## is the unknown.
I know that the work will be the same regardless the path for conservative forces, so I have:

I need to understand the mechanics involved in performing a wheelie. That includes analyzing the free-body diagram. And considering all the factors involved in performing this manoeuvre in motorbilkes.
I was checking bait cannons and potato guns on the internet because they are fun. Maybe one day I'll build my own.
First of all, these cannons use multiple sources of energy (combustion using hair spray, dry ice, etc.). I'll just consider compressed air cannons because I think they are the most...
I'm trying to design a mechanism to translate reciprocating motion into a 45 degree rotation.
Here's the idea:
A pin will push against the part marked in red, causing part of the desired rotation. Then, when the pin is pulled back, its interaction with the blue part will complete a 45 degree...
Hey!
I want to determine what bearings to use for this manual crane and the only thing i know is that it should be able to lift a wieght of 1000kg at max and that the winch should pull 1.24 m of cable/min. Im looking to find the force P to then determine C, and i think P is only the radial force...

Hi, I am trying to get the transfer function from a wall between rooms. From one side I have the force of a hammer as an input ,and in the other side of the wall (next room) I have an accelerometer. Is it possible to get the TF without know the damping, stiffness and mass of the wall partition...
From what I've gather the primary benefits to worm wheels are:
- their ability to provide high reduction ratios
- self-locking which can be useful for hoisting and lifting applications.
- Operates silently and smoothly, which reduces vibrations

If you do the sum of vertical forces and sum of moments, you're always left with an unknown.
Vertical Forces: Ray + Rby + Rcy = 59kN + 45kN (1)
Sum of Moments about A: (59 x 1.85) - (Rby x 3.7) - (Rcy x 4.8) + (45 x 6.5) = 0...
M = r x F
r = 0
∴ M = 0
But this is clearly wrong. For some reason, the "reaction moment" must exist. Why? Where does it come from? More specifically, which force(s) produces the bending moment, and at what distance(s)? Does it come from the reaction force form the wall on the left end of the...
