A spring is connected to an elastic bar as shown in the figure. The spring has a stiffness constant of 107 N/m. The bar is 70 mm long, and has an area of cross- section 10 mm2. The Young’s modulus of the bar material is 70,000 MPa. A force F = 5000 N is applied at point O along the axis of the bar and the spring. The resulting deflection of Point O in mm (rounded to one decimal place) is ______
Answer: 0.9 to 1.1
