UNIT I STEADY STRESSES AND VARIABLE STRESSES IN MACHINE MEMBERS 
Introduction to the design process - factor influencing machine design, selection of
materials based on mechanical properties -- Preferred numbers, fits and tolerances –
Direct, Bending and torsional stress equations – Impact and shock loading – calculation
of principle stresses for various load combinations, eccentric loading – Design of curved
beams – crane hook and 'C' frame - Factor of safety - theories of failure – stress
concentration – design for variable loading – Soderberg, Goodman and Gerber relations

UNIT II DESIGN OF SHAFTS AND COUPLINGS 
Design of solid and hollow shafts based on strength, rigidity and critical speed – Design
of keys, key ways and splines - Design of crankshafts -- Design of rigid and flexible
couplings.

UNIT III DESIGN OF TEMPORARY AND PERMANENT JOINTS 
Threaded fastners - Design of bolted joints including eccentric loading, Knuckle joints,
Cotter joints – Design of welded joints, riveted joints for structures - theory of bonded
joints.

UNIT IV DESIGN OF ENERGY STORING ELEMENTS 
Design of various types of springs, optimization of helical springs -- rubber springs --
Design of flywheels considering stresses in rims and arms, for engines and punching
machines.

UNIT V DESIGN OF BEARINGS AND MISCELLANEOUS ELEMENTS 
Sliding contact and rolling contact bearings -- Design of hydrodynamic journal bearings,
McKee's Eqn., Sommerfield Number, Raimondi & Boyd graphs, -- Selection of Rolling
Contact bearings -- Design of Seals and Gaskets -- Design of Connecting Rod.
