## Termotehnica

La disciplina Termotehnica, transfer de caldura si masa I Intr-un cilindru obturat cu un piston mobil se introduc kg CO2, la temperatura 50C, kmol N2 la temperatura 1000C si m3N O2 la temperatura 2000C. Initial cilindrul este izolat adiabat si pistonul este mentinut fix, inchizand volumul V1= m3. Dupa formarea amestecului si atingerea starii de echilibru se inlatura izolatia, es elibereaza pistonul iar gazul descrie un ciclu format din urmatoarele transformari termodinamice: 1-2...

## Problema Vibratii 3

Metode aproximative de determinare a pulsatiilor proprii fundamentale ale unor sisteme elastice continue Consideram o grinda simplu rezemata de lungime l=3m, cu sectiunea transversala din fig. 1. Date:

## Problema Vibratii 2

Sa se proiecteze un absorbitor dinamic intr-un sistem elastic cu urmatoarele caracteristici: Date : =20kg =190kg Se cunosc: unde n=8 spire D=5mm=0,005m R=17mm=0,017m

## Problema Vibratii

Date : =15kg =175kg =1250 L =3m v = 35 h =0,1m Cerinte : a) Ecuatiile diferentiale de miscare b) Pulsatiile proprii, vectorii proprii si modurile de vibratie c) Forta verticala la roata.Forta din arc d) Factorii reali de amplificare ai amplitudinilor deplasarilor e)Se deduc expresiile complexe ale fortelor si de aici rezulta factorii de amplificare ai fortelor
