1. a strip of high strength steel has a length of 30 cm and a cross section of 1 mm x 20 mm. the modulus of elasticity is 200 gpa, and poisson’s ratio is 0.27. it is subjected to an axial load of 15000 n, and it is instrumented with two axial strain gages, with r=120 ohms and a gage factor of 2.10. the two gages are connected into opposite legs of a wheatstone bridge (r1 and r3). the two fixed resistors are also 120 ohms, and the supply voltage is 2.5 v. the bridge is adjusted to zero voltage output before the load is applied. find the output of the bridge with the load applied.

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
