  dahhhhhhhhhhhhhh. today have my phy test. haha. cher damn devious. Qn like nvr teach b4 de.

  today de vector addition is

  2 workers supporting one pole, both at extreme ends of the pole, with 2 string holding a block of mass 250kg , and assuming that both tensions in the string are the same, find tension with a scaled diagram.   

  does any1 understand my qn ?
