Use Matlab App Designer to design a Graphical User Interface to perform the following: 1. Takes the name of an array representing an input polynomial 2. Evaluates and plots the output polynomial between user specified end points. The number of evaluation points should be obtained from a slider 3. Calculates the derivative of the input polynomial and its' backward difference approximation. Plot both on a separate area from the polynomial evaluation in step 2.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
