Transcript of EQUILIBRIO DE PARTICULA EN 2D
El dispositivo mostrado se usa
para enderezar los bastidores de
autos chocados. Determine la
tensión de cada segmento de la
cadena, es decir, AB y BC, si la
fuerza que el cilindro hidráulico DB
ejerce sobre el punto B es de
TBD = 3.50 KN
LBC = 450 mm
LBD = 400 mm
LBC = 250 mm
TAB = ?
TBC = ?
|A| = √ Ax 2 + Bx 2
EJERCICIO # 9
tan θ = co/ca = 450mm / 650mm = tan -1 = 34,69
