The mechanics learner
toolbox.
Explore elastic sections, deflection curves and transmission geometry.
10 useful places to start.
Ideal mathematical models state their assumptions; they do not establish component or structural capacity.
Rectangle section properties
Find centroidal area moments and elastic section moduli for a rectangular section.
Elastic bending stress
Calculate outer-fibre normal stress from bending moment and elastic section modulus.
Beam deflection curves
Plot deflection along a simply supported or cantilever beam for common loading cases.
Euler column buckling
Estimate ideal elastic critical load from effective length and section inertia.
Circular shaft torsion
Calculate elastic shear stress and twist for solid or hollow circular shafts.
Elastic axial extension
Calculate axial stress, strain and length change of a uniform elastic member.
Open belt pitch length
Find the geometric belt length and wrap angles between two pulleys.
Compound gear train table
Track stage ratios, speed and rotation direction through a compound external gear train.
Spur gear pitch geometry
Translate module and tooth count into common involute gear reference diameters.
Lead screw motion & torque
Relate screw lead, rotational speed, axial force and efficiency.
A few things you
can tick off.
- Compare beam boundary conditions
- Check section-property units
- Inspect a gear-train speed table
