# Two Mass Three Rope Tension Problem

• HS21
In summary, the "Two Mass Three Rope Tension Problem" is a physics problem used to calculate the tension in three ropes attached to two masses. It requires the use of equilibrium and tension principles and can be solved using algebra and basic trigonometry. The problem assumes massless and inextensible ropes and stationary masses in equilibrium. It is important in science as it illustrates fundamental concepts and has practical applications in fields such as engineering and construction.

Homework Statement
There are two blocks with weights 40N and 50N. The first block is connected to the ceiling at an angle 35 degrees to the left by rope 1 with tension T1 while the second block is connected to the ceiling by rope 3 with tension T3. In between, the first and second block is rope 2 with tension T2. Find T1, T2, T3, and theta. Refer to the attached image.
Relevant Equations
T1=(mg)/[sin(55)]

T2=T1cos(55)
What I did first is to find the tension T1 and T2;

T1=(mg)/[sin(55)]
T1=(40N)/[sin(55)]
T1=48.83N

T2=T1cos(55)
T2=(48.83N)[cos(55)]
T2=28.01N

Now I do not know how to proceed. Can someone help me?

Can you generate two equations involving the unknowns ##T_3## and ##\theta##? That would allow you to solve for both unknowns.

The magnitude of T2 is the same in both directions.
Vectors T2 and 50N are perpendicular to each other; therefore, the Pythagoras' theorem can be used to determine the magnitude of T3.
