How do you find the mass meter rule?
The weight of the rule acts through the centre of gravity at the middle of the rule. This is shown in the diagram below. where m1 is the mass hanging from the rule, m2 is the mass of the metre rule and g is the acceleration of free fall. This can be rearranged to give m2 = m1 × (d1 / d2).
What is a uniform meter scale?
Calculate the mass of the rule. Therefore, the centre of mass of the ruler is 20cm which is away from the hinge. And it is given that the ruler is in equilibrium position. Now, balancing the torques due to mass of the rod which is suspended from the ruler.
How would you use a Metre rule a 100g mass and some thread to find the mass of an apple?
With the thread tie the Apple to one end of the meter stick, and use the thread to tie the 100g mass to the other end ( you could tape the mass and Apple as a way of securing them). Now balance the mete stick across the back of a chair with the mass and apple on either side of the back.
How do you balance a meter stick?
Place several coins near one end of the meter stick. This will make that end heavier, shifting the center of gravity and the point where the stick will balance. Again, place the meter stick on your fingers and move them together.
Why is it easier to balance a meter stick than a ruler?
The more weight on your finger, the greater the force of friction. Once you change the weight anywhere on the ruler, the centre of gravity changes too. When you balance the ruler or metre stick on its end, it’s easier to find the balance point, but harder to keep the stick balanced.
What are the factors that effect of the center of mass?
The following factors affect the center of mass:
- The position of mass from the axis.
- The mass of the rigid body.
- The axis of the system.
- The distribution of mass.
What is the significance of the center of mass?
The interesting thing about the center of mass of an object or system is that it is the point where any uniform force on the object acts. This is useful because it makes it easy to solve mechanics problems where we have to describe the motion of oddly-shaped objects and complicated systems.
Why does it make sense that there is more than one way to make objects balance?
The reason why it make sense that there is more than one way to make the objects with different masses balance is that the force being applied to hold up each mass gets weaker the farther out each mass sits on the seesaw.
Why is a lower Centre of mass more stable?
Lowering your centre of gravity also helps to increase stability because it needs to be lifted higher before it moves outside of the base of support. This becomes very useful in combat sports such a jujitsu or sumo wrestling.
How does mass affect stability?
The position of the centre of gravity of an object affects its stability. The lower the centre of gravity (G) is, the more stable the object. Increasing the area of the base will also increase the stability of an object, the bigger the area the more stable the object. …
