What is the maximum tension in cable ABAD?

[Apprentice123]

A small boat hangs from two brackets, one of which is shown in the figure. It is known that the moment, on the z axis, the resulting force Ra applied in the point A of support must not exceed the value of 217 N.m, in value absolute. Determine the more value possible the traction force in cable ABAD.

Not understand the problem. What is the issue? How can I fix?

Hi Apprentice123!

It means, if the moment of R_A about that z-axis is 217 N.m, what is the tension in the cable?

The maximum tension in cable ABAD can be determined by using the equation T = Ra x d, where T is the tension, Ra is the resulting force at point A, and d is the distance between point A and point B. In this case, the maximum value of Ra is given as 217 N.m, and the distance between A and B can be calculated as 0.5 meters (half the length of the boat). Therefore, the maximum tension in cable ABAD is 217 N.m x 0.5 m = 108.5 N. However, since the question asks for the absolute value, the maximum tension would be 108.5 N x 2 = 217 N. This means that the maximum possible tension in cable ABAD would be 217 N.
