Calculate the Section modulus, Heat distortion and Snow load criteria for the created Roof. INTRODUCTION: An automobile roof or car top is the portion of an automobile that…

SECTION MODULUS: DEFINITION Section Modulus is the geometric property of the given cross-section of any shaft or beam structures. It is the direct measure of the strength of the shaft section or the beam section. Higher the section modulus of a structure, the more the resistive it becomes to bending. Section modulus is…

FENDER DESIGN: Fender is the part of an automobile frames a wheel well (the fender underside). Its primary purpose is to prevent sand, mud, rocks, liquids, and other road spray from being thrown into the air by the rotating tire. Fenders are typically rigid and can be damaged by contact with the road surface. Sticky materials,…

HOOD ASSEMBLY A car hood, also referred to as a bonnet in some other countries, is the hinged cover that rests over the engine of a front-engine vehicle. Its purpose is to provide access to the engine for repair and maintenance. A concealed latch is typically used to hold down the hood. Hood assembly have Hood Outer…

UNDERBODY COATING DEFINITION Underbody coating is usually a dense cladding (often based on rubber) applied uniformly to the undercarriage of the automobile. It is normally sprayed or painted on when the car is just out of the dealership and is clean. But even if you are getting the undercoating applied after a couple of…

BENCH MARKING DEFINITION: Bench marking in a automobile industry involves a structured comparision between similar products, services or process on some dimensions of performance. Benchmarking is a process of measuring the performance of a company’s products, services, or processes against those of competitors considered…
