The torque needed to turn the torsion spring of a mousetrap through an angle is t = k1 + k2θ. experiments produce the following data: θexp = {0, 0.2, 0.39, 0.59, 0.79} and texp = {0.2, 1, 1.3, 1.7, 2}. write a subroutine called fitmouse to calculate the constants k1 and k2 by performing a polynomial least square fit to t = k1 + k2θ using experimental data given as two row arrays. fitmouse should except experimental datasets of any size.

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
