Question
Complete the data sets for the following situations. Please show your work to explain how you determine the missing forces or distance In the second situation in Question 1, there is a 400 N person (force) on the right-hand side of the fulcrum that "balances" the 300 N person (force) on the left-hand side. If you still wanted to balance the 300 N person located 4 m away from the fulcrum, but with a 250 N person on the right-hand side (instead of the 400 N person), where would the 250 N person need to be located? 3) In the second situation in Question 1, there is a 400 N person (force) on the right-hand side of the fulcrum that "balances" the 300 N person (force) on the left-hand side. If you still wanted to balance the 300 N person located 4 m away from the fulcrum, but with a 150 N person on the right-hand side (instead of the 400 N person), where would the 150 N person need to be located? 4) In the second situation in Question 1, there is a 400 N person (force) on the right-hand side of the fulcrum that "balances" the 300 N person (force) on the left-hand side. If you still wanted to balance the 300 N person located 4 m away from the fulcrum, but with a 100 N person 1 m from the fulcrum on the right-hand side (instead of the 400 N person), you? Will need another 100 TV person on the right-hand side. Where should the second 100 TV person need to be located?Explanation / Answer
(2 )this problem belongs to translatory and ratatory dynamices of the body
the main principle involues in this condition to balance the condition
F1/F2 =d2/d1
where F1 =load to be lifted
d1 =load arm
d2=effort arm
F2 =the effort to lift the ioad
F1/F2 =mechanical advantage
so basing on this condition we solve
(1)ANS
(a) the mechanical advantage
F1 =?
F2=500N
d1=4m
d2=2m
so the codition of mechanical energy
F1/F2 =d1/d2
F1/500 = 2/4
F1 = 500*2/4
1000/4=250 N
(b)ans :
basing on mechanical advantage
F1=300 N
F2 =400 N
d1=4 m
there fore basing on above condition
F1/F2 =d2/d1
300/400 =d2 /4
1200 /400 d2
d2 =3m
to balance the mechanical advantage d2 =3m
(c) ans
the F1=600N
the weight of the board
w=F1*3/4
=600*3/4 =1800/4=450 N
(2) ANS
WE USING QUESTION NO 1
IN F1=300 N
F2=250 N
basing on mechanical advantage of rigid body
F1/F2 =d2/d1
300 /250=d2 /4
d2= 1200/250
=4.8 m
the 250 Nperson located at to balance in 4.8 m
(3) ans :
the question no 1
basing on mechanical advantage
F1=300 N
F2=150 N [instead of 400 n]
d1=4m
d2=?
basing on mechanical equalibrium
F1/F2 = d2/d1
300 /150 = d2 /4
d2 =1200/150
= 8 m
the distance of 150 N located on to balance =8 m
(4) ANS
similarly condition
force F1 =300N
Force N1 =100 N
force N 2 =100 N
d1 =4m d2=1m d3 =?
basing on mechanical advantage
F1d1 =N1d2+N2d3
300*4 =100*1 +100*d3
1200=100+100D3
1100 =100d3
d3 =11 m
the distance of 100 N os located =11 m
