Question

need a help!!! question is about cos sin tension equilibrium!

Answer 1

here is the full question

Answer 2

c) part i did fully
angles i got are for horizontal 5.75N and for vertical 4.8N
i felt like c and d parts are somehow connected so see both parts
i totally don't get d part

Answer 5

Answer 6

For the two force in d resolve them both vertically and horizontally like you did in c

For equilibrium the sum of the vertical force must equal the 7.5N weight

ALSO for equilibrium the HORIZONTAL forces must be equal (and opposite) (the weight has no horizontal component.

So you can solve the 2 equations

Answer 7

@MrNood i don't quite get it
i mean Tension 1 and 2 are here as hypotenuse what does is have to do with horizontal components?

Answer 8

sum i do get, what i don't get is how? i mean no matter what kind of triangle i draw i just don't get the right answer
and most confusing part is that these tensions have same ans as in c part
i mean tension 1 is 5.75N and tension 2 is 4.8N
so im totally lost T_T
