Question

Find T1 in the shown figure. (Assume g=10 m/s2)


  1. 220 N
  2. 240 N
  3. 260 N
  4. 280 N


Solution

The correct option is B 240 N
Using FBD

For Equilibrium
Fx=0
T1cos37=T2cos53
T1×45=T2×35
4T1=3T2
Fy=0
T1sin37+T2sin53=40 g
3T1+4T25=40 g
putting T2=4T1/3
3T1+16T13=5×40 g
T1=(5×40×10)325=240 N
