Solution Manual To Engineering Mechanics By I H Shames

in a machine, we have a collection of forces acting upon a body. these forces can act in different ways and cause different effects. for example, if one wants to take a force of 100 newton and apply it on the thumb and try to lift it up. at first, the thumb will not be lifted as there is force from fingers, elbow, shoulder etc. however, if one end holds the thumb and the other end lifts the thumb the lift will begin. this is called as a single force applied in different ways on the body and the resultant of the forces is lift. this lift is nothing but a change in the moments of these forces. this change in moments results in a change in the position of centre of mass of a system.

kinetics deals with the analysis of forces and associated motion of bodies in moving systems. kinetic measures of a body such as velocity, acceleration, acceleration rate, lateral force on a wheel etc. are given. among all these measures velocity is the most important one.

mechanics is one of the most important branches of engineering science. it studies the effect of applied forces on bodies. it is further classified into two branches, statics and dynamics. the field of the statics is further classified into kinematics, kinetics. mechanics is a branch of science that deals with effects of applied forces on bodies. mechanics deals with study of the effect of forces acting on bodies due to impulsive force or non-impulsive forces. when forces act continuously, it is called as statics. when forces are applied for short time or intermittent, it is called as dynamics. when studied, these forces are found to be applied on a body in various ways. therefore, the study of mechanics deals with the identification of those forces and their corresponding effects on the body. similarly, engineering deals with the design and analysis of machines. a machine is a set of devices used to convert one form of energy into another form. the device used to perform such conversion is called as apparatus.

as the physical quantities encountered during engineering analyses are mostly vectors, the adequate knowledge of vector algebra is required. it is very important to be familiar with the vector algebra. vector mathematics is the branch of mathematics which deals with the motion and location of a vector, and all the properties pertaining to them. vector algebra is concerned with the mathematical properties of the components of a vector. although vector is nothing but a vector quantity but it has a great significance in the study of engineering mechanics, optics and electrical engineering.
this branch of engineering mechanics deals with bodies in equilibrium and are not moving with respect to the frame of reference considered for analysis. bodies may be experiencing different forces but the configuration of these forces is such that the resultant force on the system is zero.
the term mechanics is derived from the greek word ‘mechanism’, meaning ‘working of mechanism’. in general, the term mechanics refers to the study of forces and motion of bodies. in specific, mechanics refers to the study of how materials resist and transmit forces.
heat capacity is a property of the material that describes how much the temperature changes with a change in energy. it is measured in calories or joules per kilogram. heat capacity is one of the most important physical properties of a material. it is also one of the most frequently used in engineering. it is also used to measure the efficiency of refrigeration systems. the most commonly used measure is the specific heat capacity or cp. heat capacities are typically reported as either specific heat capacity at constant pressure (cp) or specific heat capacity at constant volume (cv).
