    As Martin’s friend and attorney, I would advise him that he is the sole owner of mountain property. Since the property was purchased as a joint tenancy with a right of survivorship, Martin is now the only living tenant. Right of survivorship automatically divides the interest of the deceased tenant equally among the remaining tenants, until there is only one. Peter evidently misunderstand the right of survivorship when he indicated in his will that his share was to be transferred to his son Andrew. According to the text, under joint tenancy, all are co-owners of equal shares and may sell their shares without the consent of other owners. Their interest can be attached by creditors ( , p. 354). Since…

    The Direct Shear Test is an investigation used by geotechnical engineers used to measure the shear strength properties of a soil. It is noted that the shear strength of a material is a term used to describe a materials ability to resist failing in the direction parallel to the applied force, and therefore an important soil property to be noted by engineers. In this lab test ‘Sydney Sand’ is used to determine the relationship between a given load and a change in cross-sectional area and also show the friction angle of the soil specimen, by testing the sample using what is commonly known as a shear box.…

During the 1920’s, an era referred to as the Roarin’ Twenties, women were slowly progressing out from their stereotypical household roles to lives of entertainment and partying. In this short story, Hemingway's characters reveal the lingering differences in stature between men and women in this period. Hemingway, in this story, provides detailed descriptions and well thought out dialogue between his two main characters, an American man and a girl called Jig.

    Mount Everest is the tallest mountain in the world. Since it is 29,035 feet and has avalanches, crevasses, strong winds and is very steep, it makes it very difficult to climb. Not only is it hard to climb, imagine how hard it would be being disabled. The quote, “ Some people succeed because they are destined, but most people succeed because they are determined” really describes Mark Inglis, Erik Weihenmeyer, and Arunima Sinha.…

    Saturday Climbing at first was another plain story, but after going over the story several more times, I notice the cliff is actually representing the relationship between Barry and his daughter, Moira. It was a story that shows a single father perspective towards his daughter. W.D. Valgardson uses many symbols in his story, to help the reader gain a greater understanding of his message. He uses symbolism in two important areas: objects that have symbolic value, and setting, which relates the relation between father and daughter. Many object in Saturday Climbing have important symbolic value. For example, the "chock nut, the wire loop, the carabiner, the rope", represents the relation between Barry and Moira. "Fragile as they looked, would hold ten times his weight." Like a rope although their relation seems fragile, but it's stronger then it seems. The cliff itself is another important symbol. It shows their relation, as time pass by. Barry still views Moira as being his little girl. She appears small and innocent. She seems too young to be out in the cruel and harsh world. This view of her may never change, but Barry's level of acceptance of Moira's independence will. In the end, Barry reaches the realization all parents must come to, in time. He realizes that it is time for him to let his daughter go. He will remain there next to her supporting, but his job is limited. When there is a need he is ready to step in and resume his role as a caregiver. Until that time comes, he will give Moira "all the slack she needs while, at the same time, keeping his hands tensed, ready to lock shut, ready to absorb the shock of any fall".…
