Force - 2731 Words
What is Force?
In physics, a force is any influence that causes an object to undergo a certain change, either concerning its movement, direction, or geometrical construction. It is measured with the SI unit of newtons and represented by the symbol F. In other words, a force is that which can cause an object with mass to change its velocity(which includes to begin moving from a state of rest), i.e., to accelerate, or which can cause a flexible object to deform. Force can also be described by...

Shear Forces occurs when two parallel forces act out of alignment with each other. For example, in a large boiler made from the sections of sheet metal plate riveted together, there is an equal and opposite force exerted on the rivets, owing to the expansion and contraction of the plates. The shearing force (SF) at any section of a beam represents the tendency for the portion of the beam on one side...

Centripetal Forces - 368 Words
While the bob is moving in the circular motion, the centripetal force that is provided is the spring. The spring causes the bob to get pulled inward and while it is being pulled inward while being rotated it provides a centripetal force. If this force was suddenly removed, the Bob would still have a centripetal force due to the rope in which it hangs from causing the inward force to keep moving in a circle. But if the forces are removed than its inertia would keep it moving in a straight line at...

Centripetal force (from Latin centrum "center" and petere "to seek") is a force that makes a body follow a curved path: its direction is always orthogonal to the velocity of the body, toward the fixed point of the instantaneous center of curvature of the path. Centripetal force is generally the cause of circular motion.

Equilibrium of parallel force
To understand the conditions need for a rigid body to be in equilibrium when there are forces acting on the body from different sides.
When force is applied on a rigid body for example a ruler it can either be in equilibrium or it can be unbalance. When the force is unbalance what would happen is this motion the body can be either translational or rotational. “A body in...

Bending Moment and Shearing Force
Basic structural learning begins with an analyzing of a simply supported beam. A beam is a structural member (horizontal) that is design to support the applied load (vertical). It resists the applied loading by a combination of internal transverse shear force and bending moment. An accurate analysis required in order to make sure the beam is construct without any excessive loads which affect its strength.
A bending moment exists in a structural element when a moment is applied...

Comparing Forces Measured with a Force Table
Experimentally, we observe that the three forces applied to the ring in the center of the Force
Table balance. If forces are vectors, we expect the vector sum of these three forces to equal
zero. Experimental uncertainties will generally produce a small nonzero sum. If the
magnitude of the sum of the three vectors is not much greater than the expected uncertainties,
the measured force vectors can be said to add like true vectors.

Friction: Force and Mass - 614 Words
Purpose: To study sliding friction and to determine the coefficients of static and kinetic friction.
Theory: Friction is a force that opposes motion. Static friction prevents an objects being set into motion by an external force. Kinetic friction opposes the progress of a sliding object. Static friction is given by Fs< usn where N is the normal force between the object and its support surface and us is the coefficient of static friction. There-fore, the coefficient of static friction is...

Air resistance is an upward force exerted on a body while it is in the air and is the result of air molecules that come in contact with the surface of the falling object. This force attempts to counteract gravity and other downwards forces influencing a body. The amount of air resistance encountered by an object is dependent on two factors: speed of the...
