Speed-Torque Characteristics of DC Motor
Graph Explanation:
Y-axis: Speed (NN).
X-axis: Torque (TT).
Shape: Linear downward slope (speed decreases as torque increases).
Formula:
N=V−IaRaϕN=ϕV−IaRa,
where IaIa = armature current, RaRa = armature resistance, ϕϕ = flux.
Key Points:
At no load: High speed, low torque.
At full load: Low speed, high torque (due to armature reaction).
Applications: Used in electric vehicles and cranes for variable
Needs Assessment
Identifies what people need vs. what they currently have
Example: Survey students to see if mental health services are needed on campus
Process Evaluation
Looks at how the program is being run
Example: Are tutoring sessions happening on time and following the plan?
Outcomes/Impact Evaluation
Measures whether the program worked (did it make a difference?)
Example: Compare student stress levels before and after a mindfulness program
