How Does Ceres' Gravity Affect Copper Wire Elongation?

AI Thread Summary
The discussion focuses on calculating the elongation of a copper wire when a mass is hung from it on the asteroid Ceres. The mass of Ceres and its distance from the sun are provided, along with relevant gravitational equations. Participants are encouraged to consider how the gravitational force on Ceres differs from that on Earth, specifically referencing Young's modulus for material properties. The user seeks guidance on how to approach the problem, indicating a need for foundational knowledge in physics concepts. Understanding these principles is essential for accurately estimating the wire's elongation under the given conditions.

Homework Statement


The asteriod Ceres has a mass of 1.11x10^21 kg and a diamter 772km. Ceres orbits the sun at an average distance of 414 million kilometers.
Estimate the change in length of a 2m length of thin copper wire caused by hanging a 1.5kg mass on the wire on the asteriod Ceres.
?

If you hung the mass from the wire on Earth, how much would the wire stretch? (Consider Young's modulus.) What's different on Ceres?
 
Young's modulus...never heard of it, thanks ill look into it
 
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
I was thinking using 2 purple mattress samples, and taping them together, I do want other ideas though, the main guidelines are; Must have a volume LESS than 1600 cubic centimeters, and CAN'T exceed 25 cm in ANY direction. Must be LESS than 1 kg. NO parachutes. NO glue or Tape can touch the egg. MUST be able to take egg out in less than 1 minute. Grade A large eggs will be used.
