M1 Basics of Statics
L1 Fundamental principles & concepts: Vector algebra, Newton’s laws, gravitation,
force (external and internal, transmissibility), couple, moment (about point and about
axis), Varignon’s theorem, resultant of concurrent and non-concurrent coplanar forces,
static equilibrium, free body diagram, reactions.
L2 Problem formulation concept; 2-D statics, two and three force members, alternate
equilibrium equations, constraints and static determinacy; 3-D statics.
M2 Analysis of Structures – I (Trusses, Frames, Machines)
L3 Trusses: Assumptions, rigid and non-rigid trusses; Simple truss (plane and space),
analysis by method of joints.
L4 Trusses (contd): Analysis of simple truss by method of sections; Compound truss
(statically determinate, rigid, and completely constrained).
L5 Analysis of frames and machines.
M3 Analysis of Structures – II (Beams, Cables)
L6 Internal forces; Beams: types of loading and supports; shear force, bending
moment, and axial force diagrams.
L7 Beams (contd): shear force and bending moment diagrams and equations relating
them with external load.
L8 Cables (coplanar): assumptions, parabolic and catenary cables.
M4 Friction - I
L9 Coulomb dry friction laws, simple surface contact problems, friction angles, types of
L10 Disk friction (thrust bearing); Belt friction (flat, V).
L11 Square-threaded screw (self locking, screw jack).
M5 Friction - II
L12 Journal bearings (axle friction).
L13 Wheel friction and rolling resistance.
M6 Center of Mass & Area Moments of Inertia
L14 First moment of mass and center of mass, centroids of lines, areas, vol
