Answer 1

Respuesta:

$vr = 296.125n$

$\alpha = 88.40$

Explicación:

f(x1)=120N×Cos235°= -68.82N

f(x2)=150N×Cos260°= -26.04N

f(x3)=100N×Cos330°= 86.60N

£f(x)= -8.26N

f(y1)=120N×Sin235°= -98.29N

f(y2)=150N×Sin260°= -147.72N

f(y3)=100N×Sin330°= -50N

£f(y)= - 296.01N

VR=√£f(x)²+£f(y)²

=√(-8.26N)²+(-296.01N)²

=√68.2276N²+87'621.9201N²

=√87'690.1477N²

VR= 296.125N

Tan Ángulo= £f(y)÷£f(x)

= -296.01 N÷ -8.26N

Tan=35.83

ángulo= Arctan(35.83)

Ángulo= 88.40°
