= (3) τ = Gγ (4) IbWhere, ‘V’ is the vertical shear force, ‘Q’ is the first moment of area, ‘G’ is shear modulus, and‘𝛾’ is shear strain. Figure 3. Shear Strain and Stress DistributionThe strain, εθ , in any direction can be determined by equation five. 𝜀𝑥 + 𝜀𝑦 𝜀𝑥 − 𝜀𝑦 𝛾𝑥𝑦 εθ = + 𝑐𝑜𝑠2𝜃 + 𝑠𝑖𝑛2𝜃 (5) 2 2 2Subtracting two strains in arbitrary angles results in: 𝜀𝑥 − 𝜀𝑦 𝛾𝑥𝑦 𝜀𝜃1 − 𝜀𝜃2 = (cos 2𝜃1

Fuel Efficiency, ηBT = [percent] mf  q fSpeed Regulation of a DC motor with Pulse Width ModulationDuring this signature lab, students used a method called “Pulse Width Modulation (PWM)” toregulate the speed of a DC motor. The DC motor is probably the most important type of actuatorsused for instrumentation and control. It is widely used in agricultural machinery, medical robots,home appliances, etc. Numerically controlled lathes (mills) and 3D printing are two moderntechnologies enabled by the precision control of the speed and position of motors
