Discussion Overview

The discussion revolves around determining the braking force of a car, focusing on the necessary information and parameters required for such a calculation. It includes aspects of theoretical understanding and practical application related to vehicle dynamics and braking systems.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant provides the weight of the car and the force applied to the brake pedal, seeking assistance in calculating the braking force.
  • Another participant questions the completeness of the information, suggesting that additional details about the brake system design and road conditions are necessary for an accurate calculation.
  • A different participant mentions that knowing the time or distance could suffice for determining the braking force.
  • There is a question raised about whether this is a homework-related inquiry.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the necessary information for calculating the braking force, with multiple competing views on what details are essential.

Contextual Notes

Limitations include missing details about the braking system design, such as brake booster assistance, master cylinder diameter, caliper piston sizes, and the type of brakes used. Additionally, assumptions about the road surface and tire conditions are not addressed.

the weight of a car is 700 kg
the weight put on the brake pedal is around 30 kg to stop the vehicle moving with a speed of 50km/hr.
please help me out.

hi wrangler407! welcome to pf! :smile:

what is the full question? :confused:
 
That's not even close to enough information. How much assist does the brake booster provide? What is the diameter of the master cylinder? What are the diameters of the caliper pistons? Does the car use disc or drum brakes in the rear? basically we'd need every detail of the brake design as well as tire and road surface informatin.
 
Homework question?
