DME Syllabus:
UNIT I STEADY STRESSES AND VARIABLE STRESSES IN MACHINE MEMBERS
Introduction to the design process - factors 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 – curved beams – crane hook and ‘C’ frame- Factor of safety - theories of failure – Design based on strength and stiffness – stress concentration – Design for variable loading.
UNIT II SHAFTS AND COUPLINGS
Design of solid and hollow shafts based on strength, rigidity and critical speed – Keys, keyways and splines - Rigid and flexible couplings.
UNIT III TEMPORARY AND PERMANENT JOINTS
Threaded fastners - Bolted joints including eccentric loading, Knuckle joints, Cotter joints – Welded joints, riveted joints for structures - theory of bonded joints.
UNIT IV ENERGY STORING ELEMENTS AND ENGINE COMPONENTS
Various types of springs, optimization of helical springs - rubber springs - Flywheels considering stresses in rims and arms for engines and punching machines- Connecting Rods and crank shafts.
UNIT V BEARINGS
Sliding contact and rolling contact bearings - Hydrodynamic journal bearings, Sommerfeld Number, Raimondi and Boyd graphs, -- Selection of Rolling Contact bearings.

Mild steel allowable shear stress data book la 1.47 la illa total pages 1.44 vara dhan eruku

[msamuelwilliams]

Sir Flange Coupling ku design procedure step 1 la Iruka information Design Data Book la iruku sir page no. 7.134

[ajai]

Sir flexible coupling problem solve pannuga sir

[gowtham]

Sir formula for mt=? In flange coupling ?

[sanjayp]

Universal design procedure solluga.. Sir

[gowtham]

Sir, the first sum design of hub valve 6.15 is not possible I think so if possible please explain

[SathishKumar-chrx]

sir unit 3 viedo illa sir can you post ?

[rsuriya]

Design procedure matu eluthana marks kidaikuma

[mechboy]

Neenga endha Data book Refer panureenga Sir

[lenin_p]

Sir neenga niraiya mistakes pannirukkanga. Ungala pathutha naanga problem solve panro, appudi irukkurappa neengale thappu pannuna naanga poturathu thappatha sir. Konjam mistakes ah pathu potunga sir. Unga voice larunthu vara ans crt ah irukku, but neenga eluthurathu thappa irukku. 7:54 la first formula thappu. Na thappa solliruntha sry sir 🙏

[msamuelwilliams]

Sir Neenga Old Design Data Book use panringa nu nenaikura... New edition psg Data Book la refer pani solunga... Neenga solra page numbers and values ah enga nala find out pana mudila sir .. new edition refer pani page number solunga sir

[vigneshv]

Unit 4 problem solve panni kaminga sir
