Haley Rolsma Dr. Schnellman Eng. 15000 24 Date “Conquering the Coaster” As a girl who had always hated heights and finding myself fifteen stories in the air‚ the only thing that came to mind was if I was going to make it off the roller coaster I was riding. Conquering my first roller coaster and overcoming my fear of heights made me realize that I shouldn’t be afraid to take chances in life‚ but to be brave‚ because it may just turn out to be the ride of my life. At thirteen years old‚ I was

(MECHANICAL ENGINEERING) MECHANICAL ENGINEERING SCIENCE 3 (B58EC1) DYNAMICS LABORATORY: TRIFILAR SUSPENSION Objective: To calculate the polar moment of inertia of an assembly and using the result to predict the periodic time of a trifilar suspension of the assembly. Theory: The moment of inertia of a solid object is obtained by integrating the second moment of mass about a particular axis. The general formula for inertia is: where Ig m k I g = mk 2 = inertia in kg.m2 about the mass centre

There are many people in this world who have a plan of what they’re going to do in life by setting goals‚ and trying to conquer them. I happen to be one of those people. However‚ life changes unexpectedly and it takes a strong person to have the courage to persevere and be resilient through it all.

Dream Job Paper For most of my life the only job that ever held my interest and that really wanted was to be a stay at home mom. However after spending the last four years in college I have learned more about myself and the things I am good at. Once I got into my official major and started taking classes that actually interested me I realized I want to not only be a mom but also use what I have learned in school to excel as a career woman as well. As I approach graduation I have started to think

Environmental pollution is a big problem in modern society. It is a matter of serious concern. Pollution is the result of urbanisation and rapid industrialisation. It has been posing serious health threats. Despite growing awareness‚ environmental pollution has reached alarming level. It is an issue of global concern. Everyday conferences‚ seminars‚ discussions and debates are held to sort out this problem. Growing numbers of factories are adding to the problems of environmental pollution. They

Family Dinner Over seven years ago‚ I lived in Broome WA; I loved Broome I can remember me and my sister spending hours on Cable Beach. Cable beach had pristine white sand‚ crystal clear water and amazing sunsets. Dad used to take us camping on the beach and we would build sandcastles together and look in all the rock pools. Another experience I can remember is the staircase to the moon‚ everyone would pile on the shores of Roebuck Bay and watch the full moon reflecting off the tidal flats of the

The Catcher in the Rye Topic Tracking: Phonies Chapter 2 Phonies 1: Holden’s first mention of phonies is with Mr. Spencer. "Phony" is a word Holden uses to characterize insincere people and their language (like Spencer’s word "grand"). Phonies‚ like his fellow students‚ are more interested in playing a part or looking good than in doing or saying anything honest. Chapter 3 Phonies 2: Ossenburger is the first "phony" Holden goes into detail about. Everything we hear about him reveals hypocrisy
