Homework Statement




A mass of 5 kg is suspended by two strings, 24 cm and 32 cm long, from two points that are 40 cm apart and at the same level. Determine the tension in each of the strings.


Would the 40 cm length be the resultant or do you rearrange the 24 and 32 as head to tail vectors.

The force of gravity is (5)(9.81) = 49.05 but I don't know how to make the other two into vectors (if i have too?)

please helppp!!!!! :) :)

You don't need vector math for this, draw out the FBD of the intersect , you have two unknowns (T1, T2) and use the sum of forces at the x and at the y for this, you know they are in equilibrium as the ropes aren't breaking so their sums are always equal to zero.

I had more in here, but I'm not exactly sure what you are asking for or what you have already done, please elaborate.
