If your bike is always getting damaged in the bike storage room, you should first try to identify the cause of the damage. If it's due to overcrowding or lack of proper storage racks, you can bring this issue to the attention of the building management or whoever is in charge of the bike storage room. You can also consider investing in a sturdy bike lock and possibly finding a different storage solution outside of the building if the issue persists. Additionally, documenting the damage and reporting it to the building management can help in addressing the problem and finding a solution. **

Yes, the brightness is adjustable on most devices such as smartphones, tablets, and computers. You can usually adjust the brightness level in the settings or control panel of the device. This allows you to customize the brightness to your preference, whether you need it brighter for better visibility in bright environments or dimmer for reduced eye strain in low-light conditions. **

A simple pulse generator with adjustable duty cycle can be implemented using a 555 timer IC. By connecting the 555 timer IC in astable mode, the output pulse width can be adjusted by varying the values of resistors and capacitors in the circuit. By using a potentiometer in place of one of the resistors, the duty cycle of the output pulse can be adjusted. This allows for easy control and adjustment of the duty cycle of the generated pulses. Additionally, the 555 timer IC is a widely available and inexpensive component, making it a practical choice for implementing a simple pulse generator with adjustable duty cycle. **

Yes, the oven is not adjustable. The temperature settings are fixed and cannot be changed manually. The oven is designed to operate at specific temperature levels for different cooking functions. **

Yes, an adjustable screen can be important for various reasons. It allows users to customize the screen position to their preferred height and angle, reducing strain on the neck and eyes.

The fan of the GTX970 graphics card is not adjustable because it is designed to operate at specific speeds to maintain optimal cooling performance for the GPU. The fan speed is typically controlled automatically by the graphics card's firmware based on temperature readings to ensure that the GPU stays within safe operating limits. Allowing users to manually adjust the fan speed could potentially lead to overheating issues or damage to the graphics card if not done correctly. **
