[SIZE="2"][I've tried asking this question on math.stackexchange.com, but haven't got any responses, so I thought I'd try here] I’m building a model in a 3D simulation program (MSC Adams) and part of that model is a triangular platform which can translate and rotate in the virtual world, as...

I've attached a photo for another mechanism that is keeping me scratching my head. As far as I can tell, this is a 1DOF mechanism, with a single linear actuator allowing the fingers to rotate together about a certain point. I've highlighted in the image where I think the moving links are...

Ah that's it, thanks. That explains what the book meant when it was describing ternary and quaternary joints.

Hello all, I'm having trouble understanding how to apply the Kutzbach Gruebler equation to all but the simplest of mechanisms. As I understand it, the DOFs of a mechanism is a sum of the DOFs of all the moving links minus the sum of the all the DOFs constrained by the joints. For a planar...

Hi Jared, Thanks for your reply. Based on that, if the linear actuator produces a 10N force, F1 = F2 = R1 = R2 = 5N. Amr

A linear actuator is wedged between two solid walls as shown in the diagram below. The linear actuator is pushing outwards with a force of 10N. What are the magnitudes of the forces labelled in the diagrams? I reckon that F1 = F2 = R1 = R2. However, I'm not sure if F1 = F2 = 5N or 10N...

Hello Turin, Thanks for your reply. What I am more interested in are the forces exerted on the capsule while it is inside the water pipe. For example, I know that if I have a suction cup attached to a wall in air, the difference in pressure between the air inside the cup and the air outside...

Hello all, Consider the following scenario: I have a pipe entirely filled with water flowing through it due to a pump at one end pressurising the fluid. Imagine that underwater, I trap some of the flowing water in a capsule, completely filling the capsule with water, and then closing the...

Any thoughts?

Dear all, As I understand the venturi effect, if a flow of water passes through a constriction, its velocity increases and its pressure decreases at the restriction. The decrease in pressure allows a suction force to be produced. I am trying to use this principle in order to power a vacuum...

Homework Statement Hello. I am trying to calculate the minimum vacuum force required to keep a climbing robot attached to a ceiling. The robot body consists of a cuboid with two vacuum cups attached at either end. The robot will move using inchworm-style motion, attaching one of the cups...
