● Plagiarism will be assigned zero points to all involved. No replacement/alternate

assignments will be made available.

● Draw sketches where necessary.

● Show working of the problems for full credit. Just giving correct answer without showing

the work get only half credit for that question

● Correct choice of formulae, accurate calculations, appropriate units, well drawn sketches,

showing the work and clearly identifying your answers gets full credit for a question.

● All questions are worth equal points.

Q. 3 For the crankshaft, connecting rod and piston shown, determine the distance the piston

travels as the position of the crankshaft given by the angle θ moves from θ 35o to θ = 90o

Q.4 The 14 inch square concrete column shown in the following figure is hoisted using a

chain that is 80 in. long. If the lifting hook is placed at the midpoint, B, of the section ABC of

this chain, find the angle formed at B between the sides Ab and BC.

Q. 5 Solve the system of equations shown below using Cramer’s rule using any of the

numerical methods discussed in class. (You may cross-check your results using scientific

calculator if you like to do so.)

2A + 3B + 2C = 3

2A + B -4C = 4

A + 2B + C = 2
