Question 1 a) A cylindrical feedstock of length = 35.4 cm and diameter = 10 cm is subjected to turning using a high speed steel tool. For this tool, n and C values in the Taylor tool life equation are 0.125 and 70 m/min, respectively. The cost for hiring an operator and using the machine tool are $82 per hour. The tooling cost per edge of cutting is $5. Loading and unloading the part on to the machine takes about...

A 50-gram mass is hanging from a spring whose unstretched length is 10 cm and whose spring constant is 2.5 N/m. In the list below are described five situations. In some of the situations, the mass is at rest and remains at rest. In other situations, at the instant described, the mass is in the middle of an oscillation initiated by a person pulling the mass downward 5 cm from its equilibrium position and releasing it. Ignore both air resistance...

An ideal spring dangles from the ceiling at its relaxed length of 5 cm. A 3-kg mass is carefully hung from the end of the spring while the spring is relaxed, and then the mass is released from rest at time t = 0, which begins to stretch the spring. The spring stretches to its maximum length at time t = 130 ms when the mass reaches its lowest point. Then the mass returns upward, shortening the spring. The oscillation...
