Answer:
2) τ = F x torque increases, 3) troque decreases,
4) man approaches the pivot and the child must move away
5) Σ τ = 0
Explanation:
2) when the man moves away from the pivot his torque increases significantly, since his distance increases
τ = F x
τ = m g x
therefore the system rotates faster
3) when the child approaches the pivot, his troque decreases, because the distance decreases
τ = f x
therefore the system must spin slower
4) If we place the man and the child on the side of a scale, the movement must be the man approaches the pivot and the child must move away, so that the torque is the same and the system can reach a balance
5) the rotational equilibrium expression
Σ τ = 0
is the one that describes the equilibrium of a system with several forces
Following are the solution to the given points:
For question 2:
- If the guy was further to the right, say the [tex]5^{th}[/tex] unit,
[tex]\to W_2\times d_2=80\times 5=300\ units[/tex]
- Since this value is larger than [tex]W_1\times d_1=30\times 8=240\ units[/tex]
- As just a result, the boards will lean towards the guy, and will tumble to the right.
For question 3:
- If the girl was [tex]6^{th}[/tex] units closer to a pivot,
[tex]\to W_1\times d_1=30\times 6=180 \ units[/tex]
- This value is once again less than [tex]W_2\times d_2=80\times 3=240\ units[/tex]
- As just a result, the boards will tilt towards the guy, and will fall to the right.
For questions 4 and 5:
- Whenever experimenting, verify that the mass you utilize and the distance you travel are carefully measured.
- Since even a tiny quantity of ambiguity in such measures can produce unexpected results.
