thanks
2. the system is in equlibrium, therefore all forces are balanced.

resolving vertically: T1 cos30 + T2 cos50= 20 x 9.81

resolving horizontally: T1 sin30= T2 sin50.

solve simultaneously to get T1 and T2
3. Thankyou so much!!!! i have the exam as well and i never understand those questions but that makes it sooo much clearer lol! xxx
4. Just one thing kosy, 9.8 should be used.

You lose 1 mark per question for using 9.81
