mechanical applied to machines

[dexx]

Hello, guys!

I must follow the course of mechanics applied to the machines but I did not follow rational mechanics, only analysis 1/2 and general physics. .
I would like to know if any of you can tell me what the rational mechanics arguments are necessary to tackle the mechanical examination applied to machines.

Thank you all! :redface:

but is there prophesiivity?
I don't know about the new one, but at the old order the two exams had little in common.

we say that there is a semi-prophetivity. I explain: officially enough are the prophesiivity of analysis 2 and general physics, but the professor requires that the student has already supported rational mechanics. . .

 

[ironlomo]

at the applied mechanical parmesan university can also be supported without rational support.

Obviously, being one of the final exams of the course, it would be better to have already given rational mechanics.

but it's absolutely not prophetic.

in my faculty there was absolutely no bias and many supported mechanics applied before rational mechanics.
However, there were cases - it seems to me that yours is one of these - in which, despite the fact that the professor "hotly suggested" to support another examination first. in my faculty this situation existed for machines: I believe that no one in his time had ventured to present himself to the oral of machines without first supporting technical physics, given the professor's insistence.

with regard to the rational mechanics arguments useful to the understanding of applied mechanics I would think especially of the kinematics and dynamics of the rigid body: instantaneous centers rotation, speed and acceleration of the points of a body, moments of inertia and inertia products, etc., useful for a series of topics (dened wheels, articulated mechanisms, dynamics and rotors balancing, etc.).

then maybe the programs have changed, eh, we talk about almost 15 years ago now (sigh).

the program should be this:

definitions of group, machine, mechanism, film couple.
fundamentals of mechanics: cardinal equations of dynamics, principle of almbert, equation of kinetic energy, equivalent systems, reduced systems.
mechanical performance:definition, performance of series mechanisms, efficiency of parallel mechanisms.
Mechanical adjustment: Dynamic conditions of the machines, characteristics curves, conditions of regime, adjustment in the period and in the regime.
Mechanical vibrations: elementary vibratory phenomena, systems at a degree of freedom, vibration isolation.
dynamics of rigid rotors:balance of rotors.
flexible rotors dynamics:flexional critical speed, jeffcott rotor.
mechanisms: cinematic and dynamic study of the rotational push mechanism.
mechanical transmissions:transmissions with belt, with friction wheels, with toothed wheels, ordinary and epicycloidal rotisms, cams and props, joints, rolling and crawling bearings.

Thank you for your help.. I will concentrate on the topics suggested

the answers on axes are not enough!
