CONCENTRATED LOADS on Cables Example Problem // How to solve for the unknowns on loaded cables

In this video I go over an example problem on how to solve for the maximum mass that can be placed on the cable given that it can only sustain 400 newtons of tension in it. We also find what the sag of the cable is due to this load. We do this by using the Method of Sections and the Method of Joints to analyze the internal forces in the cables and how they relate to the external forces. Using the sum of the forces in the X and Y directions and the sum of the moments we can solve for these unknowns.

Hi sir. I'm having trouble with this question. It has the exact figure and exact value except the value of load F is given but Tmax is not. And need to find the tension ab. How to do it sir? Thank you

It’s still the same process. You set up the free body diagrams of the different joints and sections of the cable and then use the method of joints and the method of sections to solve for the unknown forces. In your case the load F will become a known force and Tmax will be an unknown force. Here are some links to videos explaining the methods of sections and joints: kzfaq.info/get/bejne/qZOEd5WIxLi3lJ8.html kzfaq.info/get/bejne/i9iXpZCg0t3Tm4k.html

Hi sir, i have a problem of rope with concentrated load. The problem is,I have a rope with 6 meters length, at the first end of rope (Point A pinned at x=0, y=0) and the second end of rope (Point B pinned at x=4,y= -1) then divided the 6 meters rope to put a 2 concentrated load with the same mass( .5kg ) so there has 3 segments and each segment is 2 meters. The question is. what is the x and y position of 2 concentrated load after i hang it into the rope? please help.. thank you in advanced.

That’s a pretty complicated problem unless they give you a few more pieces of information. What you would need to do is get a bunch of equations using the method of sections and the method of joints and then solve for those unknown variables with a system of equations. Here are some of my videos explaining these concepts if you don’t understand them: Equilibrium equations: kzfaq.info/get/bejne/hq5hZr1zzJuxkZ8.html Method of joints: kzfaq.info/get/bejne/qZOEd5WIxLi3lJ8.html Method of sections: kzfaq.info/get/bejne/i9iXpZCg0t3Tm4k.html Concentrated loads on cables: kzfaq.info/get/bejne/f7SfeLqCyp6xcZ8.html
