AI Thread Summary
To build an efficient mouse trap car that can travel over 175 feet, focus on maximizing wheel performance and ensuring a straight trajectory. Use the supplied materials effectively, particularly the CD wheels and brass axles, while keeping them well-lubricated for reduced friction. The assembly should be precise, with all components securely fastened to maintain stability during movement. Consider the weight distribution on the balsa chassis to enhance distance traveled. Overall, attention to detail in construction and material use will be crucial for achieving the project goals.

Hey everyone, My name is Brandon and I have been assigned a mouse trap car project for my high school engineering class.

Homework Statement



The following are the specs:
-I need it to go the maximum distance
-Must travel in a straight line
The materials supplied:
-4 ea. CD's (wheels)
-2 ea. 1/4" brass axles
-4 ea. 1/4" beveled rubber washers
-4 ea. 1/4" flast rubber washers
-4 ea. 1/4" flat steel washers
-2 ea. Balsaa wood chassis rails, 36" long max.
-1 ea. 1/8" x 3" x 12" balsa deck
-1 ea. 1/8" x 12" brass tube
-1 Small mouse trap (4.5 x 10 centimeters)
-1 Small zip tie
-Fishing line cut to any length

Homework Equations


My concern is figuring out how to build the most efficient mouse trap car to go upwards of 175 feet. In addition I am allowed to use my own materials but the ones listed above must be used. Also, the mouse trap it self can NOT be modified. Does anyone have any suggestions?
 
Physics news on Phys.org
I did one when i was in SEA (Science and engineering academy) camp a few summers back. I found that if you keep the axels well lubricated and sturdy, it would be a good start. just make sure you get all of the pieces put to gether as well as you can and don't cut corners. that's the best i got, but nobody else seems to be helping
 
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...
