Answer:

The result is an unbalanced force to the right or acting in the a-axis.

Explanation:

For the first diagram, we propose a sum of forces on the X & y axes and include these forces arithmetically, i.e. the upward forces with a positive sign and the downward forces with a negative sign. Forces to the right with positive sign and forces to the left with negative sign.

ΣFx = 0

+ 1 +3 = Fx

Fx = 4 [N] (units of Newtons]

ΣFy = 0

-2 + 2 = Fy

Fy = 0

Therefore the result is an unbalanced force to the right or acting in the a-axis.

In the parallel spring system, the springs are positioned so that the 37 N weight stretches each spring equally. The spring cons
Reptile [31]

Answer:

x = 5.29 m

Explanation:

given,

weight of stretch = 37 N

left-hand spring constant (k₁)= 2.7 N/cm

right hand spring constant(k₂)= 4.3 N/ cm

spring are connected in parallel

F = F₁ + F₂

F = k₁x + k₂x

F = (k₁+ k₂)x

37= (4.3+ 2.7)x

7 x = 37

x = 5.29 m
