    What is the tension in a system of 2 pulleys when acceleration is 0?

    Homework Statement Calculate the tension T in case a, b, and c if acceleration = 0. Ws = weight of the bottom pulley W = weight of the weight Homework Equations mg - T = m*a The Attempt at a Solution For a, it just seems like T = Ws + Wm since the bottom pulley is connected to...

    How Do Horizontal Components Affect Total Tension in a Spring Balance?

    So W*cos(α) + W*cos(β) = Fb?

    How Do Horizontal Components Affect Total Tension in a Spring Balance?

    For the FBD, it's just tension pulling up and weight (mg) pulling down. T = W?

    How Do Horizontal Components Affect Total Tension in a Spring Balance?

    Upper pulley FBD = Tension to the left at angle α and I guess some type of support holding it up? Lower pulley FBD = Tension to the left at angle β as well as weight pointing down. For the lower one, it's supported by the Y component of that string, right? T*sin(β) = W T = W/sin(β) If...

    How Do Horizontal Components Affect Total Tension in a Spring Balance?

    Homework Statement Fb is the spring balance which measures the total tension in the string. So T1 + T2 = Fb The system is at rest so a = 0. Weight W is hanging as shown in the diagram. T1 corresponds with angle α and T2 corresponds with angle β. ONLY THE HORIZONTAL FORCE CONTRIBUTES TO...
