There are 25 equilibriums of trigonometry taught.Just learn them by heart.
they are called

prasarana suthra x 6
aakalana suthra x 4
gunana suthra x 3
bhaga kona suthra x 12

They are based on 3 main equilibriums and those 3 x "sadarana visadhum".Then you have to work around 4 vaththa chapa and know how to work with questions.

menna podi gaanak

Thirasata anshaka 30 k aanatha thalayak matha 6kg skandhayakata sahallu thanthuwak adaa thanthuwa thalaya mudune athi kappiyak udin panna 8kg skandhayak ella nidahas karanu labe . 6kg matha garshana balaya 30N nam paddathiye podu thwaranaya haa thanthuwe aathathiya soyanna ??

Menna ans eka

F=ma to the 8kg to the vertical direction

80 - T = 8a -------(1)

to the 6 kg in the direction of the inclined place

T - 30 - 60.cos 60 = 6a
T - 60 = 6a ------ (2)


(1) + (2)
20 = 14a ===> a = 10/7 ms^-2

from (1)
T = 480 / 7 N

Hari neda?
