Answer:

W = 270.9 J

Explanation:

given,

F(x) = (12.9 N/m²) x²

work = Force x displacement

dW = F .dx

the push-rod moves from x₁= 1 m to x₂ = 4 m

integrating the above

$\int dW = \int_{x_1}^{x_2}F. dx$

$W = \int_{x_1}^{x_2}F. dx$

$W = \int_{1}^{4} (12.9 x^2) dx$

$W = 12.9\times [\dfrac{x^3}{3}]_1^4 dx$

` $W = 12.9\times [\dfrac{4^3}{3}-\dfrac{1^3}{3}] dx$

W = 270.9 J

work done by the motor is W = 270.9 J
