When is the mechanical advantage greater than one?
The IMA of a machine is greater than 1 whenever the output force is greater than the input force.
What can you tell about two objects if one floats and one sinks?
First, buoyancy force must be defined. A force is just a fancy way of saying weight. But, the buoyancy force of an object is an upward acting force on an object in fluid (water in my example) and is equivalent to the weight of the volume of water that the object sitting in the water displaces. So, boats displace a huge volume of water and thus their buoyancy force, which is acting upwards, is very large; so, a boat will float. So, if two objects that displace amounts of water equal to their volume (think 2 blocks of substances) are put into water, and one sinks while the other floats, then the one which sank has a higher density than water and the one which floated has a lower density than water. But, if one object was shaped like a bowl and was floating, then all you can say is that it has a greater buoyancy force than the other object which sank. Note that when an object sinks, it still has a buoyancy force, but this force is not as large as the weight of the object itself, which is acting downwards, overcoming the buoyancy force. This topic gets even more confusing when talking about foams of various geometries, but I hope what I said kind of helps.
What is the difference between the equation for force and the equation for weight?
There are many equations for force, depending on the setup, the machinery, the origin of the force, etc. The equation for weight is one of them. It's the right one to use when the origin of the force is mutual gravitational attraction between two masses. <><><><><> The force acting on an object is mass times acceleration. The weight acting on an object is the force of gravity, and is G (the universal gravitational constant, about 6.67 x 10-11 N (m/kg)2) times mass1 times mass2 divided by distance squared. This is normally expressed in newtons, but if you normalize to G and mass2 you discover that the force due to gravity is the same as mass1.
Which equation can be used to solve for the mass of the object?
Thanks to Isaac Newton's Second Law of Motion, one can determine the mass of an object if he or she knows both the force acting upon the object and the acceleration of the object. Newton's equation is as follows: F = ma; where "F" is the force acting upon the object, "m" is the mass of the object. and "a" is the acceleration of the object. Solving for "m", the equation can be rewritten as: m = F/m. Substitute force for "F", and acceleration for "a", and you can solve for the mass of the object.
What is a jewel in math terms?
I don't know of use of the word jewel in math terms. But a joule (pronounced the same as "jewel") is the energy exerted by a force of one newton acting to move an object through a distance of one metre.
How are the input and output forces of the parts of a compound machine related?
In a compound machine, the output force of one part becomes the input force for the next part. This allows the overall machine to multiply the force applied to it by using a series of simple machines working together. The output force of the compound machine is the product of all the individual input forces and mechanical advantages of each part.
Adding a force acting in one direction to a force acting in the opposite direction is the same as?
Having no force acting at all, as the forces will cancel each other out. This results in a net force of zero.
How is algebra used in enginerring?
one example is to solve for the forces in each part of a system/structure if it has an external force acting on it.
Adding a force acting in one direction to a force acting in another direction is the same as anewton?
When adding forces acting in different directions, you need to consider both the direction and magnitude of each force. If the forces are acting in opposite directions, you need to subtract the force in one direction from the force in the other direction to find the resultant force. In this context, the Newton is a unit of force, not a mathematical operation.
What is adding a force acting in one direction to a force acting in the opposite direction called?
It is the same as adding a positive and adding a negative number
What is Engine relay?
Mechanically and electrically, a relay is a generic term for a part of a machine which uses a small force to actuate a larger one.
What is a machine with one movement?
A machine with one movement is a simple machine that performs a single type of motion, such as a lever or a pulley. These machines are typically used to amplify force, change the direction of force, or increase the distance over which force is applied.
What will be the definition of co-linear force and coplanar force?
The difference is that one is co-linear force is one dimensional and co-planar force is 2-dimensional. Co-linear force is the force which is acting along a single line, whereas co-planar force is the force which is acting along a single plane.
Adding a force acting in one direction to a force acting in the opposite direction in the same as adding a?
Forces are vector quantities. This means they have both a magnitude and direction associated with them. If you add vectors going in the opposite directions it is the same as subtracting one from the other. Therefore, the resultant force is the difference between the forces.
How are the input and output force of the parts of a compound machine related?
In a compound machine, the input force is applied to the first machine and then becomes the output force for the next machine in the sequence. The output force of the first machine becomes the input force for the next machine, and so on. Therefore, the input and output forces of the parts of a compound machine are related as they are transferred from one machine to the next within the system.
How do you find the net force acting on an object?
To find the net force acting on an object, you need to sum up all the individual forces acting on the object. If the forces are in the same direction, add them. If they are in opposite directions, subtract the smaller force from the larger one. The net force is the total sum of all the forces acting on the object.
When more than one force is acting on and object the blank determines the motion of the object?
Net force determines the motion of the object. If the net force acting on an object is not zero, the object will accelerate in the direction of the net force.
