Homework Statement
hello i have a problem with this question.
the cylinder shown in fig1 has a mass of 10 kg. if theta = 45 and the system is in eqlibrium determain the tension in cables ca, cb.
Homework Equations
all i want is the equations and a guide to the i.e what each component is m=mass or g=gravity. and it would be really helpful is some provided outher useful formula for similar questions. as i have 3 or 4 and one includes a spring but i don't want to be cheeky and ask all 3 questions so if i got a list of formula i think i could apply them ok providedi know each component.
The Attempt at a Solution
10x9.81 = 98.1 and because the system is in equlibrium the total tension must equal 98.1.
Tca= 30=w1=10x 9.81
98.1/sin30 =196.2N
Tcb = Fca cos 45 = 196.2 cos 45 = 138.59N
these two answers are far to big i think and i don't know of any way to find the tension
