Part C - Engineering Profession (10 marks) Part-1: Circle the right answer. Only one answer is acceptable 1. The relatio
Question-2 (10 marks: 10%): (CLO3:100%) Human Factors Indicate if each statement in the following table is True or False Statement The goals of ergonomics are to ensure comfort, safety, and quality of products. The goal of considering human factors in the engineering design is to fit human capabilities to the machine. The first step in acoustic treatment is to erect barriers between the source and the listener. Designers should use anthropometric data to design products to be suitable for the 50 percentiles of users. In selecting the buttons to be placed in the middle of a TV remote control, the buttons that have the highest frequency of use and time (duration of use) should be placed in the middle. In a car, the force needed to adjust the seat belt is an example of physiological factors. The size of the engine in a car is an example of anthropometric factors. A remote control is curved in the middle to allow users to easily access buttons in the middle. This is an example of psychological factors. The temperature of air inside a car is an example of physiological factors. The position, size, and color of buttons in the instrument panel of an airplane are example of psychological factors. Question-3 (25 marks: 25%): (CLO2:100%) Need analysis and problem formulation Toys have gained increased use in the contemporary world.
