Tags Dynamic Pulley Pulley system System In summary, the conversation is about a physics problem involving two boxes connected by wires and the calculation of their acceleration and work done. The approach involves using the equations F = ma and Wd = 2T*sA + (60-3T)*sB, with careful attent...
Give two reasons why the efficiency of a single movable pulley is not 100%. How does torque work? Explain with examples and drawings. How to solve pulley problems without differentiation? What factors might account for the loss of energy/efficiency in a pulley system?
How to solve inclined plane problems in physics How to find acceleration on an inclined plane with friction 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?
Why Does Dust Float? Examples of Forces in Everyday Life and How They Affect Things Newton's 3 Laws of Motion: Force, Mass and Acceleration How to Solve Projectile Motion Problems: Applying Newton's Equations of Motion to Ballistics
With so much information stored in such a tiny amount of space, a hard drive is a remarkable piece of engineering. That brings benefits (such as being able to store 500 CDs on your iPod)—but drawbacks too. One of them is that hard drives can go wrong if they get dirt or dust ...
In summary, the conversation discusses a problem involving finding the angular velocity of a pulley on an incline. The equations and attempts at a solution are provided, with a focus on determining the difference in tension in the rope due to the pulley's mass and angular momentum. The ...
He asked Musk whether taking on a problem that automotive giants with their billions of research dollars had failed to solve was too ambitious. The CEO answered that he looked at only two things before embarking on anything. First, can it be done? Are we bre...
Clutches and gears partly solve this problem. (A clutch is a mechanical "switch" that can disengage an engine from the machine it's driving, while a gear is a pair of interlocked wheels with teeth that changes the speed and torque (turning force) of a machine, so it can go faster or...
The intelligence community will be tempted to "solve" the intelligence problem by throwing resources at collection systems. The path to intelligence reform: "changes in the intelligence craft must go beyond redrawing the organizational chart and redesigning its chain of command." (National Affairs) Ev...
