How to make Hinge Joint object kind of rotate left and right

Hi! I am trying to make a rope swinging system, right now it works pretty good with child cube and cyllinder with hinge joint, but I have problem with that when I am pressing the horizontal movement (I made a simple script, here:

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class AddForceSwing : MonoBehaviour {
6.     public Rigidbody RopeBottom;
7.     // Use this for initialization
8.     void Start () {
9.      
10.     }
11.  
12.     // Update is called once per frame
13.     void Update () {
14.         float horizontal = Input.GetAxis("Horizontal");
15.         float vertical = Input.GetAxis("Vertical");
16.  
17.         RopeBottom.AddForce(transform.forward * vertical, ForceMode.Acceleration);
18.         RopeBottom.AddForce(transform.right * horizontal , ForceMode.Acceleration);
19.     }
20. }
21.  

) It is attached to a child cube which is adding the force to the bottom cyllinder (I made it using tutorial:

, but I use only one cyllinder) And the issue is that the object doesnt rotate to the left or right. How can I do that? I made a short drawing of what the movement I'd like to do:
