Summary

1 / 6

Past student reviews · Heidi Ploeg

One student found the course covered a wide range of difficult material that was hard to synthesize, noting there was always a significant amount of work due.

What you’ll be able to do

  • Sketch failure envelopes for both brittle and ductile static failure theories and use these to estimate safety factor against potential static stress failure

  • Calculate safety factor for high cycle fatigue of steel components

  • Assess safety factor for straight cut spur gears against bending and surface fatigue failure

  • Predict the failure rate of components based on property and load distributions and estimate the cost of these failures in terms of human life and limb

  • Quantify specifications of belt and pulley systems for successful transmission of power between parallel shafts

  • Quantify specifications of rolling element bearings for successful shaft support

Student experience

the class

Past student reviews · Heidi Ploeg, Ryan Kershner

Students described Heidi Ploeg as incredibly helpful with homework, while Ryan Kershner's lectures were considered convoluted with insufficient examples. Exams were reasonable but not easy, and tests were open book and note.

Recent recorded grades — Spring 2025: 3.32 GPA, 65.3% A/AB (n=167 letter grades); Fall 2025: 2.72 GPA, 34.2% A/AB (n=155 letter grades); Spring 2026: 3.12 GPA, 40.4% A/AB (n=161 letter grades).

difficulty & workload

Past student reviews · Heidi Ploeg

One student found the course covered a wide range of difficult material that was hard to synthesize, noting there was always a significant amount of work due.

Past student reviews · Ryan Kershner

A student noted that most homework topics were not covered in lecture, requiring extensive reading from the textbook, which they described as not being great.

Topics

  • Loads, stresses, deflections, material selection, fatigue failure, and finite elements.
  • Mechanical power transmission components, including gearing, bearings, shafting, and frictional devices.

Skills

  • Estimate safety factors for static and fatigue failures, including sketching failure envelopes and calculating high-cycle fatigue limits.
  • Assess gear safety factors for bending and surface fatigue, and quantify rolling element bearing specifications for shaft support.
  • Analyze loads, stresses, and deflections; select materials; and apply finite element concepts to machine design.

About this estimate

The course’s semester-average GPA, not an individual student’s grade. The center uses 5 same-season terms, weighted toward recent results.

The range uses the finite-sample 80th-percentile rank of absolute errors from earlier same-season forecasts. Each forecast uses only records from earlier terms. At least four forecasts are required; bounds are rounded outward and limited to 0–4. This is an empirical estimate: changing instructors or grading policies can reduce its coverage.

About this comparison

1280 courses over the same term, each with at least 30 recorded letter grades. Cross-listed courses count once. GPA is not a measure of difficulty or teaching quality. The typical course is the median by recorded grade count; tied values are not counted as lower. Grade counts describe course scale, not unique students or typical section size.

Descriptions compare GPA with this group’s average: at least 0.20 higher or lower; otherwise close to average. Section size uses median recorded enrollment: small up to 30, mid-sized 31–99, large 100+. Lectures and discussion/lab sections are described separately.
