### How to measue synchronous (toothed) belt tension

04.04.2019· Belt tension can also be measured, or estimated, by causing the belt to deflect by a given amount (typically 1/64 inch per inch of belt span, or 0.4 mm per 25 mm of belt span) with a specified force. Often referred to as the force-deflection method, the minimum and maximum forces necessary to produce the specified deflection for a given tension are calculated via formulas. Note that this ...

Tension Formula Questions: 1) There is a 5 kg mass hanging from a rope. What is the tension in the rope if the acceleration of the mass is zero? Answer: The mass, m = 5 kg; the acceleration, a = 0; and g is defined. T = mg + ma. T= (5 kg) (9.8 m/s 2) + (5 kg)(0) T = 49 kg-m /s 2 = 49 N. 2) Now assume an acceleration of + 5 m/s 2 upwards.
