time-dependent temperature and ρ(r ⃗,t ) the density. These are examples of scalar valued fields. On the other hand, force or flux are examples of vector valued fields. Furthermore, stress is an example of a rank-two tensor field.
Material Point notion
If we consider a body with volume ”V” which separates parts of a physical space with its surface “A”, the material point “P” is an internal point in this body which has volume ∆V and mass ∆m. Figure 1 depicts part of a body discretized with material points.

mechanics. It implies that there is force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces. He hypothesized this theory while in the bath. Unfortunately his theory only covered fluid mechanics and didn’t elaborate completely on force. However he was one of the first scientists to discover buoyancy and the displacement of fluids. By 17th century Italian astronomer Galileo Galilei…
The History of the Development of the Four Fundamental Forces
Nature has a total of four fundamental forces. The forces include gravitational, electromagnetic, strong nuclear and weak nuclear force.
Gravitational force is the force of attraction between all masses. Every object in this universe is pulling upon other objects. Many scientists came up with logics to explain the science behind gravitational forces. The first one to try was Aristotle in around 330 BC. Aristotle believed Earth and…
1. The following events related to untochable force:
(1) coconuts falling from the tree to the ground
(2) Attract magnetic iron plates
(3) footwear be worn after long use
(4) Budi push the beam to shift to the right
The above events involving untouchable force is the number of events ....
a. 1 and 2
b. 1 and 3
c. 2 and 4
2. Amir and Badu are playing tug of war. Amir pull to the left with a force of 200 N while Badu pull to the right by the force of 350 N. resultant force generated is ....…
In legal terms, force majeure is a commonly included clause in a contract that is intended to save the parties from legal reparation should they fail to fulfil their obligations because of an “act of god” or natural disaster. Force Majeure, a film by Ruben Östlund, provides the perfect example of the contract made in marriage not carried out when one of the main characters, Tomas, abandons his wife and children in the wake of an avalanche. Euripides’ play Medea also depicts a broken marriage…
The lab we completed today was “Equilibrium of coplanar forces”. The objectives of todays lab was to study the composition and equilibrium as well as study the rectangular resolution and equilibrium of coplanar forces.
Principles being examined:
The main principle being examined in this experiment is the fact that several forces that line on a plane and pass through the same point can be balanced by a single force that is passing through the same point. We do this by finding the…
Is there a relationship between the mass of an object and the force of static friction and force of kinetic friction of that object? If so, what type of relationship is there?
Friction is a type of force that is created when two surfaces move across one another. Static friction is friction between two or more solid objects that are not moving relative to one another. Kinetic friction is the amount of friction between two objects that are moving relative to each other.…
look at what factors drive the change process forward and what factors resist the change. Lewin’s force field analysis provides a method for evaluating these driving forces and resisting forces (Lindauer, 2015). This method identifies these driving forces and resisting forces and helps leaders develop methods for encouraging and promoting the driving forces while minimizing or reducing the resisting forces to change initiatives.
The MSPAC identified the need for change nearly a decade ago. The…
1) You need to discuss the effect of compressive force, tensile force, shear force, bending force on structural member
Compressive force on timber: - The effect of a compressive force on a timber is a change in structure of a material and to carry a load within its limits.
Tensile force on timber: - The tensile force is the pulling force exerted on both the ends of a timber. Both the ends of a timber will undergo tension.
Shear force on timber: - The shear force is the…
The foot and ground exert an equal and opposite force on each other. This is known as the ground reaction force.12 The position and acceleration of the runner's center of mass regulates the direction and magnitude of the ground reaction force. For instance, a runner sprinting from a standstill. Throughout the initial phase of acceleration, the body is inclined forward and therefore the center of gravity falls in front of the contact surface. After many gait cycles, the runner reaches top speed…
