Truck suspensions often have "helper springs" that engage at high loads. One such arrangement is a leaf spring with a helper coil spring mounted on the axle, as in the figure below. The helper spring engages when the main leaf spring is compressed by distance yo, and then helps to support any additional load. Consider a leaf spring constant of 6.05 x 105 N/m, helper spring constant of 3.60 x 105 N/m, and y₁ = 0.500 m.

Combined Loading

Any functioning component, such as machine parts, structural members, pressure vessels, and so on, are all under the influence of more than one force. When anybody is under the influence of more than one force such as shear forces, bending moments, axial forces, torsion, and so on, then such body is said to be under combined loading. A very practical example of combined loading is the crankshaft of an internal combustion engine (IC engine). The crankshaft of the IC engine is under high rpm, which is caused due to the torsional forces. Due to the presence of piston, counterbalances, and internal imbalances, the crankshaft experiences lateral forces and due to the rise in temperature, the crankshaft undergoes thermal expansion, which pulls the crankshaft along the axial direction and lateral direction. The presence of unbalanced loads along the periphery of the crankshaft also induces a bending moment.

Question

**Truck Suspension and Helper Springs**

Truck suspensions often include "helper springs" to manage high loads effectively. In this illustration, a leaf spring with a helper coil spring is mounted on the axle. The helper spring engages after the main leaf spring compresses by a specified distance \( y_0 \), providing additional support.

### Diagram Explanation
- **Truck Body:** The structure supported by the springs.
- **Helper Coil Spring:** Positioned above the axle, it activates to support extra loads after initial compression of the leaf spring.
- **Leaf Spring:** Installed beneath the axle, provides primary suspension.
- **Axle:** Connects the truck's wheels, pivotal in load distribution.

### Given Values
- **Leaf Spring Constant:** \( 6.05 \times 10^5 \, \text{N/m} \)
- **Helper Spring Constant:** \( 3.60 \times 10^5 \, \text{N/m} \)
- **Initial Compression Distance (\( y_0 \)):** \( 0.500 \, \text{m} \)

### Questions

(a) **Compression of the Leaf Spring:** For a load of \( 4.55 \times 10^5 \, \text{N} \), calculate the compression.

(b) **Work Done in Compressing the Springs:** Determine the energy required.

This setup ensures efficient load management in trucks, enhancing safety and performance.

Two massless springs with different spring constants k₁= 100 N/m and k₂ = 10 N/m are aligned vertically, as shown in figure 1. A block of mass m = 0.12 kg is placed on the bottom spring. The distance between the top of the box and the top spring is h = 0.35 m. You compress the bottom spring Ay = 0.3 m from its equilibrium position (figure 2). When you let go, the box flies up (figure 3) and compresses the top spring (figure 4). Treat the upward direction (↑) as positive, such that the compression of the top spring is a positive displacement. What is the maximum compression of the top spring due to the flying box?
