For anyone playing along, I've got a solution. The force in BC is the reaction force from F in a simple lever setup. Then this is the force acting at the top of member CD which creates the torque.

Thank you for your help!

So would the torque around D just boil down to = F_b*lambda*sin(omega)? Where F_b is = [ F*(alpha/2)*sin(theta) ] / [ (alpha/2)*sin(phi) ]

Anyone able to help?

Hi, It's fixed on the pivot. Apologies for the lack of detail!

Hi guys, It's been a while since I've done much resolving forces stuff, and I'm struggling to make sure what I'm doing is right. I have a setup like below, and I want to find the torque around point D due to the force acting at point A. I've had a couple attempts but I feel like I'm just...

Hi Nidum, Thanks for your reply. I've drawn the force vectors that I think are happening, as seen below. Is that correct? The main issue I'm having is actually determining the value of F_b and whether or not it interacts along BC or if it acts at an angle on BC.

Hi all. Brushing up on some of my force and torque stuff so I can do some modelling in software. Homework Statement I have a system as shown in the picture. A force F acts at point A, which is the end point of the lever AB. Connected to the lever is a link BC, and connected to BC at point C is...

Ah, yes, this is my fault for the miscommunication. I know the pressures of the cylinders at any given time, and from that, I can calculate the force of each without having to consider the payload mass.

Hi Dr. D. Apologies for bothering you, but I'm still slightly stuck, and I think I'm thinking about this the wrong way. My methodology is as follows: The cylinder forces are known. We have 3 equations for every component in the linkage. The unknowns in these equations are the forces that each...

Thank you for all your help so far! I'll keep trying and will be back if I have any trouble. Many thanks once again!

Much appreciated Dr. D. I've managed to find the cylinder forces, I'm just now struggling to make sure my FBD equations are correct. My procedure for completing the FBD has been to separate all linkages into single components. Then take the sum of all the forces in the Y direction = 0. Then...

I've managed to do the kinematic analysis and every link has been defined in the global coordinate frame via vector loop analysis/ kinematic constraint equations. How would I go about the Principle of Virtual Work?

Hi! I'm trying to complete a static force analysis on the bar linkage shown below. The goal is to find the payload mass in terms of the cylinder forces and everything else in a static environment. To simplify things I've made the assumption that the mass of the payload in the bucket acts at...
