Account for friction. Any object being pulled by a rope that experiences a "drag" force from friction against another object (or fluid) transfers this force to the tension in the rope. Force from friction between two objects is calculated as it would be in any other situation - via the following equation: Force due to friction (usually written F r) = (mu)N, where mu is the friction coefficient between the two objects and N is the normal force between the two objects, or the force with which they are pressing into each other. Note that static friction - the friction that results when trying to put a stationary object into motion - is different than kinetic friction - the friction that results when trying to keep a moving object in motion. Account for acceleration after defining the forces. Gravity isn't the only force that can affect the tension in a rope - so can any force related to acceleration of an object the rope is attached to. If, for instance, a suspended object is being accelerated by a force on the rope or cable, the acceleration force (mass × acceleration) is added to the tension caused by the weight of the object.

The event occurred in the city of Nashville hosted by a kendama blog called the "Kensession Stand". The event was called the "Nashville Kendama Battle", and was held at 12th South Taproom.

Let's say we have a system with a 10 kg weight (m 1) hanging vertically connected by a pulley to a 5 kg weight (m 2) on a 60 degree ramp (assume the ramp is frictionless).To find the tension in the rope, it's easiest to find equations for the forces accelerating the weights first.

The F-Type incorporated new modifications unknown to kendamas at the time. The F-Type had two small holes drilled in the middle of each side of the sarado, and also used a sturdier string that was unlikely to break. The two string holes in the sarado offer more fluidity of play as well as the option to switch the kendama between left handed or right handed. Note that, usually, physics problems assume ideal pulleys - massless, frictionless pulleys that can't break, deform, or become separated from the ceiling, rope, etc. that supports them. Use multiple strands to support a hanging object. Finally, let's consider an object hanging from a "Y-shaped" system of ropes - two ropes are attached to the ceiling, which meet at a central point from which a weight hangs by a third rope. The tension in the third rope is obvious - it's simply tension resulting from the gravitational force, or m(g). The tensions in the other two ropes are different and must add up to equal the gravitational force in the upward vertical direction and to equal zero in either horizontal direction, assuming the system is at rest. The tension in the ropes is affected both by the mass of the hanging weight and by the angle at which each rope meets the ceiling. [9] X Research source
