Is the pulley massless and frictionless? That's the key.physics kiddy said:I have attached a pic with my question. I want to know if T1>T2 or not.
Careful! That's not true. In general you'll have to solve for the tension in the string by applying Newton's 2nd law.As much as I know, Tension in a string = Earth's Gravitational force.
I don't know what you mean. T1 and T2 are tensions. Regardless of the size of the mass on the ends of the string segment, the tension on both sides of a massless and frictionless pulley will be the same.physics kiddy said:T1 has a mass greater than T2.
technician said:Agree completely with DocAl and will add that the tension in a string is the same everywher... all the way along it.
Are you sure that T2 refers to the tension between m and the pulley and not between m and m?physics kiddy said:The tension between 2m and pulley is T1 and between m and pulley is T2.
In that case, your question has already been answered.physics kiddy said:Yes, I am sure.
See post #6.physics kiddy said:I can't figure out where the answer is. Please explain it once again. Thanks
Tension in a string is caused by a pulling force applied at both ends of the string. This creates a resistance to the force and results in the string becoming taut.
Tension in a string is typically measured in units of force, such as Newtons. This can be done using a tension meter or by calculating the force required to stretch the string a certain distance.
T1 and T2 refer to the tension at two different points along the string. T1 is the tension at one end of the string, while T2 is the tension at the other end. The difference between T1 and T2 is dependent on the amount of force applied at each end and the properties of the string.
Not necessarily. The tension at each end of a string can vary depending on the force applied and the properties of the string. T1 may be greater than T2 if more force is applied at that end, but this is not always the case.
The longer the string, the more tension it can withstand before breaking. This is because longer strings have more material and can distribute the force applied over a larger area, resulting in less tension at any given point along the string.
