│ Cost Accounting Fundamentals: Cost Sheets and Cost Behaviour
Types of Cost Based on Cost Behaviour
Based on cost behaviour, costs are mainly divided into the following three types:
- 1. Fixed Cost:
Fixed cost remains constant regardless of the level of production or activity within a certain range.
Example: Rent of building, salary of manager, insurance premium. - 2. Variable Cost:
Variable cost changes in direct proportion to the level of production or activity.
Example: Direct materials, direct labour, packing expenses. - 3. Semi-Variable Cost:
Semi-variable cost contains

1. Scientific Formulas in Electronics
Q1. Explain the three kinds of formulas with examples.
- Definition: A formula invented for a new concept. It is accepted as true by agreement. Example: C = Q / V, R = V / I.
- Law: A formula describing a relationship that already exists in nature. It is true because experiments verify it. Example: Coulomb’s Law, F = k · (Q₁Q₂) / d², where k = 9 × 10⁹ N·m²/C².
- Derivation: A formula obtained from other formulas using mathematics. It is true because mathematical
Structural Loads, Foundation Engineering, and Seismic Design
1. Types of structural loads
a structural load is a force or action acting on a building that produces stress, strain, deformation or displacement. Proper assessment of loads is essential because structural failure can occur when the load-carrying capacity of a structure is lower than the actual load acting on it. Structural loads may produce compression, tension and shear. Tos v unit 01 part i 2026
1. Dead load
