#### Description

• Stress and deformation of solids-rods, beams, shafts, columns, tanks, and other structural, machine and vehicle members. Topics include stress transformation using Mohr's circle; shear and moment diagrams; derivation of elastic curves; and Euler's buckling formula. Design problems related to this material are given in lab.
• Requirement for the following UMCP engineering programs: Aerospace Engineering; Bioengineering; Civil and Environmental Engineering; Fire Protection Engineering; Mechanical Engineering.

#### Goals

The student will develop and/or refine their knowledge in the following areas:
• Stresses and deflections in shafts
• Stresses in beams – bending and shear
• Beam deflections using singularity functions and superposition
• Statically indeterminate rods, shafts, and beams
• Thermal stresses and deflections in rods
• Stress transformation and principal stresses using Mohr’s circle
• Material failure theories
• Stress analysis under combined loading – 2D and 3D
• Eccentrically loaded columns
• Stress concentrations under static and fatigue loadings
• Linear elastic fracture mechanics for static loadings

#### Topics

• Moments of inertia for plane areas
• Stresses and deflections in shafts
• Stresses in beams – bending and shear
• Beam deflections using singularity functions and superposition
• Statically indeterminate rods, shafts, and beams
• Thermal stresses and deflections in rods
• Stress transformation and principal stresses using Mohr’s circle
• Stress analysis under combined loading – 2D and 3D
• Column analysis
• Stress concentrations and fatigue strength

#### Learning Outcomes

• an ability to apply knowledge of mathematics, science, and engineering
• an ability to function on multi-disciplinary teams
• an ability to identify, formulate, and solve engineering problems

#### Class/Laboratory Schedule

The University of Maryland follows the Maryland Higher Education Commission's policies on "contact hours;" specifically, one semester hour of credit will be awarded for a minimum of 15 hours, of 50 minutes each of actual class time, exclusive of registration, study days, and holidays.
