Question 1: (40 MARKS)
E-Hailing Bicycle Management System
Case Study:An e-hailing company that rents out bicycles needs a system to manage its bicycles, users, and borrowing process. Each user can borrow up to 2 bicycles at a time, specifically for families with children 18 years or below. The system must track the bicycles (name, make, type, and availability) and users (name, ID, and borrowed bicycles).
The company also wants to ensure that the system uses a multidimensional array to store information about the bicycles.
Requirements:
Add and View Bicycles:
Borrow Bicycles:
Return Bicycles
Display Borrowed Bicycles and Search for a bicycle
Create a menu-driven program to implement the above.
Sample Output:
Add Bicycle
View All Bicycles
Borrow Bicycle
Return Bicycle
View Borrowed Bicycles

Question 1
1. A solid shaft of 1.55 m is used as a tractor propeller (prop) shaft. The shaft twists through 1.8 while rotating at 900 rpm. The diameter of the shaft is 60 mm and the modulus of rigidity is 85 GPa.
Calculate
1.1 The maximum shear stress in the shaft
1.2 The power transmitted by the shaft.
2. The tractor has undergone minor modifications to increase the transmitted power by 20%. The solid shaft is replaced by a lighter hollow shaft of the same material, with a dimeter ratio of 2:1.
Calculate the suitable dimeters of the hollow shaft.
