An object of weight `500 kg_(wt)` is lifted by using a hydraulic press. The radii of the cross sections of the pump piston and press piston are 10 cm and 20 cm, respectively. Calculate the effort required to lift the object. Calculate the displacement of the load if the effort is moved through a distance of 20 cm.

Explanation

To solve the problem, we need to calculate the effort required to lift an object using a hydraulic press and the displacement of the load when the effort is moved through a certain distance.

### Step 1: Calculate the Weight of the Object
First, we need to calculate the weight of the object in Newtons. The weight is given as 500 kg (wt). To convert this to Newtons, we use the formula:

\[ \text{Weight (W)} = \text{mass (m)} \times g \]
