With what force magnitude must the man pull on the rope if he is to rise (a) with a constant velocity? After looking at the solution, the part that confuses me is the 2T. I don't understand why 2T=mg+ma (m is the mass of the man-pulley) is the equation that we can use. ...
In summary, the problem involves two masses connected by a rope on a pulley, with one mass on an incline of 30 degrees and the other hanging vertically. The goal is to find the tension in the rope. The correct solution involves using the equation F=ma and considering the forces acting ...
Newton's Second Law of Motion states that the sum of the forces acting on an object of constant mass is equal to the mass of that object multiplied by its acceleration. We can also express this statement as an equation: ΣF = m × a where: Σ (sigma) denotes the summation of forces...
In analytic geometry a plane curve is usually considered as the graph of an equation or function, and the properties of curves are seen to depend largely on the degree of the equation in the case of algebraic curves (i.e., curves with algebraic equations) or on the particular function in...
If a conveyor starting button is ON at this time, a motor 11 drives to tighten the belt 1. When the traveling speed of the belt 1 reaches the range of the stationary values, the tension begins to decrease inversely, and the loosening operation continues until the following equation is set...

Sorry if it's dumb and repetitive, but if you had a string on a pulley with two weights on each side, each exerting a force of 80N would the tension on the string be the same throughout? Would the centre of the string have a tension of 0? I think students often get confused ...
Great job on using the correct equation for this problem! Your answers for (a) and (b) are correct. To find the tension in the rope, you can use the equation F=ma again, but this time for the package. The package is not accelerating, so the only force acting on it is gravity, ...
1. A motor control device comprising: a drive controller to output a drive command signal that drives an electric motor of a motor system, the motor system including a belt driver defined by a drive pulley, a driven pulley, and a belt wound on the driven pulley and the drive pulley, a...
engagement with one of the opposing belt spans. The tensioner pulleys displace the opposing belt spans closer together upon positive actuation of the tensioner system in the positive direction. The use of the variable tension pulley system on an upper body exercise machine using a fan is also ...
