3. A work station is to be located 3 m from a conveyor belt generating a sound power of 0.004 W, 4 m from a machine with 0.005 W sound power, and 6 m from a machine with 0.009 W sound power. Calculate: (a) the noise level at the work station if the sources rest on a hard surface but there are no sound reflections from walls or ceilings (b) the noise level at a work station 1m closer to...

A factory worker pushes a 26.5-kg crate a distance of 4.3 m along a level floor at constant velocity by pushing horizontally on it. The coefficient of kinetic friction between the crate and the floor is 0.27 Suppose the worker pushes downward at and angle of 340 below horizontal. (a) What magnitude of force must the worker apply? (b) How much work is done on the crate by this force? (c) How much work...

A work cell in a local manufacturer has a workstation with 4 machines and each unit needs to pass through each machine in order to be completed. Each machine has a production capacity of four units per hour. What is the process time of the work cell in minutes per unit?
A work cell has four stations, and each unit produced at the cell needs to be processed by all of the stations in series. (The same unit cannot be worked on by four stations simultaneously.) The capacity of each station is (Station #, # of Machines, units per hour), (S1, 1, 4), (S2, 1, 5), (S3, 1, 6), (S4, 1, 8). What is the process time of the work cell in minutes per unit?
Q4: 3 marks A manufacturer has three machines I, Il and Il installed in his factory. Machines I and Il are capable of being operated for at most 12 hours whereas machine III must be operated for at least 5 hours a day. She produces only two items M and N each requiring the use of all the three machines. The number of hours required for producing 1 unit of each of M and N on the three machines are...
