Friction - the property of two tengent objects which produce a tangential stress on their tengent points that gives the pids a what prevent friction or sliding on another is called friction or force , the meaning of friction is often considered to be the force of friction . Types of friction - There are often two types of friction ....... (1) static fiction (2) Dynamic friction (1) Static friction - If two objects touch each other are in equilibrium ,they arise at the tengent point is called static friction . (2) Dynamic friction - the friction arising at tge tengent point of one body at the point of sliding or moving at the other body is called dynamic friction . Limiting friction - If one body is in state of sliding an another body ie in the state of marginal equilibrium . frictio...
Traingle law of force => If two forces acting simultaneously an a point are represented by the two sides of a traingle taking an order corresponding to their magnitude and direction so their resulting force can be represented by the third arm of the traingle in the opposite order or three forces acting on a point if in magnitude and direction , represented by all the three arms of a traingle in order then these forces will be in equilibrium . Lami's theorem - According to Lami's theorem , if three forces acting in a point remain in equilibrium , then each forces will be proportional to the sin angle between two other forces. Suppose, three forces P,Q and R are working at a point O, the forc...
@ Civil En gineering content @ (By Er. Akash Gupta) Civil engineering :- civil engineering is a part of engineering science .It is arguably the oldest engineering discipline. The built environment encompasses much of what define modern civilization . Building and bridges are the first constructions that come to mind in engineer's as they are the most important part or civil engineering . Civil engineering deals with the design , construction and management of the physical and natuarly built environment, include public work such as road ,highway, bridges, buildings , culverts, canals , dams and other component of construction .Road ,railroad and airports are designed by transportation engi...
