For example, the coefficients for the expansion of are: Note 2: As the power of a decreases by 1, the power of b increases by 1. In each term, when you add together the powers of a and b together you get n. So, Example 1: Find the expansion of . Solution: The coefficients are 1, 4, 6, 4, 1 (from Pascal’s triangle). The expansion is: Example 2:

The steel wire extends from x = –2.000 m to x = 0, the copper wire extends from x = 0 to x = 2.000 m, and the tension is negligible. The temperature is then lowered to 20.0°C. Assume the average coefficient of linear expansion of steel is 11.0 ( 10–6 (°C)–1 and that of copper is 17.0 ( 10–6 (°C)–1.

[1] Here, = k/ρc, is the thermal diffusion coefficient with dimensions of length squared over time. The initial condition specifies the value of u at all values of x at t = 0. This condition is written as follows: u(x,0) = f(x) [2] In problem 5 we have f(x) = sin(0.4πx) and in problem 13, f(x) = x.

Next, we just consider the functions (n(x) = sin nx. These are also orthogonal on the interval 0 < x < (. The resulting expansion (1) is called the Fourier sine series expansion of f and will be considered in more detail in section 1.7. ... Using the second identity in (8) of section 1.3 one has ((n(x), (m(x)) = sin(nx) sin(mx) dx = - cos(n-m)x ...

Equation [10] can only be satisfied if the sine term is zero. This will be true only if xmax is an integral times . If n denotes an integer, we must have [11] We have an infinite number of solutions for X(x), as the integer n goes from 1 to infinity. We can write an individual solution as Xn(x) = sin(n x/xmax).

The band in Figure P10.19 is stainless steel (coefficient of linear expansion = 17.3 × 10–6 °C–1; Young’s modulus = 18 × 1010 N/m2). It is essentially circular with an initial mean radius of 5.0 mm, a height of 4.0 mm, and a thickness of 0.50 mm. If the band just fits snugly over the tooth when heated to a temperature of 80°C, what is ...

For this expansion you are able to use some of your existing machines that are currently not being used. Four years ago you paid $250,000 for these machines and the current market value of the machines is $110,000. You have been using a 5-year straight-line full depreciation on these machines. There is no need to buy any additional equipment.
