Simple Machine: A machine with few or no moving parts. Simple machines make work easier. Examples: Screw‚ Wheel and Axle‚ Wedge‚ Pulley‚ Inclined Plane‚ Lever Compound Machine: Two or more simple machines working together to make work easier. Examples: Wheelbarrow‚ Can Opener‚ Bicycle Inclined plane: A sloping surface‚ such as a ramp. Makes lifting heavy loads easier. The trade-off is that an object must be moved a longer distance than if it was lifted straight up‚ but less

The advantages and disadvantages of multimedia There are a couple of advantages and disadvantages to using multimedia in communication. I’m only going to a list a few important ones below. If you are interested to know more‚ visit one of the given websites by just following the links. Advantages: • It is very user-friendly. It doesn’t take much energy out of the user‚ in the sense that you can sit and watch the presentation‚ you can read the text and hear the audio. • It is multi sensorial

trigonometric and exponential functions in the polar coordinate system for annular sector plates subjected to uniform loading. The salient feature of the solution development includes the derivation of a closed-form solution for the fourth-order partial differential equation governing plate deflections in the polar coordinate system. The series solution developed in this study is not only very stable but also exhibits rapid convergence. To demonstrate the convergence and accuracy of the present method‚ several

02 Euler’s Method for Ordinary Differential Equations After reading this chapter‚ you should be able to: develop Euler’s Method for solving ordinary differential equations‚ determine how the step size affects the accuracy of a solution‚ derive Euler’s formula from Taylor series‚ and use Euler’s method to find approximate values of integrals. 1. 2. 3. 4. What is Euler’s method? Euler’s method is a numerical technique to solve ordinary differential equations of the form dy (1)

Advantages of marginal costing (Relative to the absorption costing) Preparation of routine operating statements using absorption costing is considered less informative for the following reasons: 1. Profit per unit is a misleading figure: in the example above the operating margin of Rs2 per unit arises because fixed overhead per unit is based on output of 5‚000 units. If another basis were used margin per unit would differ even though fixed overhead was the same amount in total 2. Build-up or run

behaviors‚ depending on with whom they interact- their differential associations. A prison groups may differ in whether they view a behavior as deviant or not. This theory suggest that people in prison act deviant when they feel encouraging about violating norms then adhering to them. These prison woman use the “neutralizing beliefs” to reduce the apparent disapproval of the deviant behavior. In this show you definitely see the modification of differential association’s theory with regards to the positive

The salary gap between genders has been a predominant issue in the sports arena. Women are continually paid less than their male counterparts‚ but men experience pay differentials between each other in some sports. In male dominated sports‚ such as hockey‚ baseball‚ and basketball‚ there is a variation in an individual’s salary that adversely affects the team’s performance and vice versa. In a capitalist society‚ everybody is paid what their work is worth. Sports such as hockey‚ basketball‚ and

Maxima and Minima First Derivative Test 1) We are given the function First‚ we find the derivative: We set the derivative equal to 0 and solve: Since the domain of f is the same as the domain of f’‚ 4 is the only critical number of f. Testing: x < 4 | f’(0) = -8 | f is decreasing | x > 4 | f’(5) = 2 | f is increasing | By the First Derivative Test‚ x = 4 is a local minimum. 2) We are given the function First‚ we find the derivative: We set the derivative
