Question 13
Object "m" is suspended by a string (string 1) connected to the ceiling. String 2 connects "m1" to another object "m2" below it. Each object has a mass of 20kg.
a. Sketch the objects showing the masses and strings.
b. Draw the Free Body Diagram for each mass, and label each force.
c. Are either (or both) masses in equilibrium? Why?
d. What is the tension in string 2 Show your work.
What is the tension in string 1 Show your work.
f. Which tension is greater and why?

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
