How to find acceleration on an inclined plane without friction Two coplanar forces act on an object as shown. Which diagram shows the resultant F of these two forces? When drawing a free-body diagram, how should vectors be drawn? How to find the coefficient of friction ...
PROBLEM TO BE SOLVED: To provide a method for measuring a friction coefficient capable of suppressing the influence of a solid lubricant and more accurately evaluating the temperature dependence of the friction coefficient of a metal base material and hard particles themselves. A method for measuring...
aWe next went on to discover “why” it is important and that is because doctrine can save the hearers. 我们其次发现“为什么”它是重要的,并且那是,因为教条可能保存听者。[translate] aI cannot test the friction coefficient, but me was told 2 test how to see which parts are rougher: 我不...
In summary, the conversation discusses an experiment conducted to find the coefficient of friction on rubber using a ramp and photo-gates to record the time and velocity of a car-like object. The experimenter is trying to determine the correct variables to use in their calculation and ...
In designing machinery, would we prefer to use materials with a larger or smaller coefficient of friction? Explain your reasoning. Explain how and why the velocity of an object changes when it falls in a viscous fluid. I am a solid. I have 2 plane surfaces. I have no edge and no ...
I don't think I will be able to find the friction coefficients between the threads or between the nut and screw thread. The manufacturer of the anti-seize product isn't going to know that, but the manufacturer of the vehicle, and I doubt they would provide that. It probably exists somew...
Along with their resistance to reacting with other chemicals, fluorine atoms also play a role in giving PTFE a low coefficient of friction. The coefficient of friction is a measurement of how easy it is for two substances to slide by each other -- the harder it is to slide, the higher ...
Tire manufacturers sometimes publish a coefficient of rolling friction (CRF) for their tires. You can use this number to calculate how much force it takes to push a tire down the road. The CRF has nothing to do with how much traction the tire has; it is used to calculate the amount of...
