Easter Holiday Assignment
Review units 7.05 and 7.06 and answer the questions at the end of each unit.
Election Holiday Assignment
Page 145: # 1a-e in addition to the one i gave in class.
Week Two
The aim this week is to connect with last week's concept and apply it to these two questions. You don't have to print the questions, i only want you to write the answers in the notebook.
1. State the conditions necessary for an object
to be in equilibrium
Hello and welcome to 9th Grade. We begin by looking at these slides. You are free to download them, but i think viewing from this site will be adequate. When you are done viewing, i would like you to respond to question #1-3, page 55 (by that we are discussing the 3 questions as specified on slide 25) from you textbook using the "post a comment" link on this page. Pls remember to put your name.
Hope you enjoyed the slides. In addition to the question on slide 25 ie #4, page 55, i will also want you to go to page 74(exam questions) and answer #1-2 and 4 in your notebook. Thanks.

Hello all,
It's Jola. Here are my answers:
1. Force and distance
2.The principle of moments is that the clockwise moment and the anti-clockwise moment need to be equal in order to make the bar in equilibrium.
And if the object is in equilibrium, the sum of the clockwise moment about any point is equal to the sum of the anti-clockwise moment about that point.
3. a) m = f * d = 4N * 4m = 16Nm
b) m = f * d = 6N * 2m = 12Nm
c)The plank will not balance, it will tip towards the right side.
d)1N
e)Clockwise
I hope my answers are appropriate and correct.
Hi this is Tobi
1.Force and Perpendicular distance from the pivot.
2. If an object is equilibrium: the sum of the clockwise moments about any point is equal to the sum of the anticlockwise moments about that point. The sum of forces in one direction must equal the sum of forces in the opposite direction.
3. a. 4Nx4m=16Nm b.6Nx2m=12Nm c.The plank will not balance, it will tip to the right. d. 1N
e. anticlockwise.
Hello It's Ibrahim here.
1. The two factors are, force and perpendicular distance.
2. The principle of moments states that the anticlockwise moment is equal to the clockwise moment.
If the object is in equilibrium the sum of the clockwise moments about any point is equal to the sum of the anticlockwise moments about that point.
3 a. Moment about O=
4N *4m
= 16Nm
b. Moment about O =
6N * 2m
= 12Nm
c. The plank won't balance, it will tip towards the right.
d. 1N
e. anticlockwise
it's Betrand
1)distance and force
2)The principle of moment stats tat the anticlockwise must be the same as the clockwise.
3)
A 4N*4m=16Nm
B 6N*2m=12Nm
C the plank will not be balance it will tip mto the right
D)1N]
E)anticlockwise
it's Betrand
1)distance and force
2)The principle of moment stats tat the anticlockwise must be the same as the clockwise.
3)
A 4N*4m=16Nm
B 6N*2m=12Nm

Hi Gabriel here
1)force exerted by an object & perpendicular distance between force and pivot.
2)For an object to be in equilibrium, the total clockwise moment must be equal to the anticlockwise moment.
3)(a)Clockwise= 16Nm
(b)Anticlockwise= 12Nm
(c)The plank will not balance. it
will tip clockwise(to the right)
(d)1N
(e)Anticlockwise
I am Avinash
1)force and perpendicular distance form the pivot
2)
The principle of moments states that, when an object is in equilibrium, the sum of anticlockwise moments about any point equals the sum of clockwise moments about the same point.
The sum of the clockwise moments equals sum of the anticlockwise moments when the body is in equilibrium.
3)a)4*4=16
b)6*2=12
c)the plank will not balance and it will tip on the right side
d)1N
e)clockwise
This Oyinn
1.it depends on the force exerted on it and the perpendicular distance from pivot
2.the principle of moments says that when an object is in equilibrium,the sum of anticolockwise moments about any pivot is equals to the sum of the anticlockwise moments when the body is in equilibrium.
3.(a)4*4=16-clockwise
(b)6*2=12-anticlockwise
(c)it wouldn't balance because its not equal, and the plank will tip to the right side which is clockwise.
(d)1N
(e)anticlockwise
hi, this is Jola. concerning the answer for Thursdays class about what converts A to DC, the answer is a rectifier
I hope
��
Hi this is Ayomide
The answer to the question from the last class which says what convert DC to AC in an inverter is an "Oscillator".
Ayushi here........
Mr Yinka tell us the answer please...!!!
