No. Where did you get the 0.09 m distance? (Remember: You need the perpendicular distance to the pivot point. Perpendicular to what?)Fusilli_Jerry89 said:The Attempt at a Solution
0.154F-(17)(0.09)
F=10N
Is this right?
Since you are trying to find the torque exerted about the corner edge by the spool's weight, what you need is the perpendicular distance from the corner to the line of the force. Since the weight is vertical, the perpendicular distance will be the horizontal distance between the corner and the center of the spool. That distance is not 0.20 m, although it may look like that since your diagram is not drawn to scale. 0.20 m is the radius of the spool, not the distance to the corner edge.Fusilli_Jerry89 said:the 0.20 is the horizontal distance from the middle of the spool to the edge. Just the radius.
Fusilli_Jerry89 said:ok I see how the distance would get less and less as you go down the circle. But Ihave no idea how to calculate it?
Fusilli_Jerry89 said:with that triangle i got 58 degrees from the origin and then two 61 degrees. Ur asking for that 58 degrees right?
The formula for calculating force required to pull a 17N spool over an 11cm edge is: Force (F) = Mass (m) x Acceleration (a). In this case, the mass would be 17N and the acceleration would be the force needed to overcome the resistance of the edge, which can be calculated using the coefficient of friction and the angle of the edge.
The coefficient of friction is a measure of how easily one surface slides over another. It is affected by factors such as the texture and material of the surfaces. The higher the coefficient of friction, the more force will be required to overcome the resistance of the edge.
Yes, the force required can be reduced by decreasing the coefficient of friction or by changing the angle of the edge. Using a smoother surface or lubricant can also help reduce the force needed.
The units used for the calculation should be consistent. For example, if the mass is given in kilograms, the acceleration should be in meters per second squared. It is important to double check the units to ensure accuracy in the calculation.
Some potential sources of error in this calculation could include inaccurate measurements of the spool or edge, variations in the coefficient of friction due to changing surface conditions, and human error in inputting the values into the formula. It is important to be mindful of these potential errors and take steps to minimize them for more accurate results.
