In most practical applications the dimensions do not scale down by the same amount. Using the formula’s given in class/lectures derive the overall scaling factor for the mass and deflection if the width, thickness, and length is scaled down by 10x, 100x, and 5x respectively.

Consider a career path. Discuss one example of a current materials challenge in that field. What solutions might exist?

A centrifugal pump with an impeller diameter of 30cm and speed 1800RPM operating at its best effiecieny point develops a head of 30m and a flow of 3900L/min. while requiring power of 24kW. This pump is scaled up to provide a flow of 11000L/min. and a head of 75m. Determine the impeller diameter, speed, and a brake power of the new pump.

One option for a material product’s end of life is recycling. Why is recycling of metals more successful than that of polymers? What are the additional challenges in recycling polymers compared to metals?

Using the Angström–Page method, calculate the average horizontal insolation in Hamburg in May and in October with PS 40% and 60%, respectively.

A 2024-T3 aluminum bar has rectangular cross section dimensions of 2" x 0.5". The length of the column is 9.0 inches.

A) Calculate the transition slenderness ratio (Sr)_D for this column. [Answer should be 69.9]

B) Calculate the slenderness ratio for your assigned column length. [Answer should be 62]

C) Calculate the maximum unit load (P_cr/A) for the bar. Indicate whether the column is a Johnson or Euler column. [Numerical answer should be 25296 psi but I don't know Johnson or Euler]

Visit a local auto repair operation like walmart or peboys and observe battery replacement, oil change, jack operation, and general safety on site.

Develop a inspection form to assess a work facility.

Develop a inspection form targeting specific workplace hazards associated with an activity and equipment.

Coordinate with a work organization to conduct a general inspection of a work facility or work unit and conduct a detailed inspection of a specific workplace activity and related equipment.

Develop a report with inspection results, including a risk assessment of hazards identified and recommendations for hazard control if deficiencies are noted.

Coordinate with a work organization to complete a job safety analysis of a work task. The write-up should summarize the analysis and a completed analysis form should be included in the paper submission.

The College of Business and Public Administration at Benton University has a copy machine on each floor for faculty use. Heavy use of the five copy machines causes frequent failures. Maintenance records show that a machine fails every 2.5 days (or A = 0.40 failure/day). The college has a maintenance contract with the authorized dealer of the copy machines. Because the copy machines fail so frequently, the dealer has assigned one person to the college to repair them. The person can repair an average of 2.5 machines per day. Using the finite-source model, answer the following questions:

A) What is the average utilization of the maintenance per person

B) On average, how many copy machines are being repaired or waiting to be repaired

C) What is the average time spent by a copy machine in the repair system (waiting and being repaired)?
