AI Thread Summary
The discussion focuses on seeking assistance with formulas for a review worksheet that is partially completed. Specific formulas mentioned include the acceleration component along an incline, calculated as gsin(theta), and the force of friction determined by the coefficient of friction multiplied by the weight of the body. Participants express a willingness to help by asking for specific questions and guidelines related to the worksheet. General tips for using Excel formulas are provided, including basic functions like SUM and AVERAGE, as well as more complex functions like IF and VLOOKUP. Overall, the conversation emphasizes collaboration and support in completing the review worksheet.

8th one is a pretty simple one.

The box's acceleration component along the incline is gsin(theta)
theta is the angle of incline

here, the force of friction is (co efficient of friction) * (weight of the body)
Accleration = netforce / mass
guess yourself what net force would be!
 


Sure, I would be happy to help you with the review worksheet. Can you please share the specific questions that you need help with? Also, it would be helpful if you could provide the instructions or guidelines for the worksheet so I can better understand what formulas to suggest. In the meantime, I can offer some general tips for using formulas in Excel. For basic calculations, you can use formulas such as SUM, AVERAGE, MIN, MAX, and COUNT. For more complex calculations, you can use functions like IF, VLOOKUP, and COUNTIF. Let me know how else I can assist you.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
