True False In general, there is an inverse correlation between the frequency and the magnitude of a disaster process.
If a particular disaster has a high frequency of occurrence, then it also has a large return period recurrence interval.
In general, the larger and more energetic the disaster event, the shorter the return period between such events. The annual likelihood of a tornado that kills 10 people is less than that of an earthquake killing the same number of people. The likelihood over 20 years of a hurricane that kills people is greater than that of an earthquake that kills people. Of the 40 worst disasters between and , the most frequent mega-killers were earthquakes.
True False 7. In the period between and , 26 of the 40 worst disasters occurred in a belt running from Bangladesh through India and Iran to Turkey.
Asia dominates the list of the 40 worst killing disasters of the last three decades of the 20th century, with almost 86 percent of the fatalities occurring in these regions. The locations of the worst dollar-loss disasters for the insurance industry present a very different picture than the list of worst locations for fatalities in the last three decades of the twentieth century.
Today, the world growth rate for human population is rapidly declining. By the year B. At present, the world population is growing at about 1. If 6 billion people stood shoulder-to-shoulder with each person having his or her own 1-metre by cm space, the entire world population would fit inside a square fence about 42 kilometres on a side.
True False 8. When carrying capacity decreases, populations collapse in mass die-offs. The difference between a world population in the year of 3. A very slow exponential growth rate of population can continue indefinitely on an Earth of finite size and resources.
Beginning in the eighteenth century, discoveries in science, medicine, and public health caused death rates to drop dramatically. World population growth presently varies greatly from one region to another. The rate of world population growth has increased from 1. The age distribution of a population relative proportions of people of different ages is not important when considering the growth rate of that population.
In the last 50 years of the 20th century, the world population of humans grew from 2. True False 9. The majority of Canadian disasters from to are not due to natural causes. The list of most costly Canadian disasters is dominated by earthquakes, volcanoes, and tsunami. The fact that Canada has not experienced a great geological disaster is in part due to the relatively short history of the country.

Ans: CE 0. A thin strip of rubber has an unstretched length of 15 in. If it is stretched around a pipe having an outer diameter of 5 in. All rights reserved. This material is protected under all copyright laws as they currently exist.
No portion of this material may be reproduced, in any form or by any means, without permission in writing from the publisher. A thin strip of rubber has an unstretched length of mm. If it is stretched around a pipe having an outer diameter of mm, determine the average normal strain in the strip. Determine the average normal strain developed in each wire. The wires are unstretched when the lever is in the horizontal position.
The two wires are connected together at A. If the force P causes point A to be displaced horizontally 2 mm, determine the normal strain developed in each wire. The rubber band of unstretched length 2r0 is forced down the frustum of the cone. Determine the average r0 normal strain in the band as a function of z.
When the force P is applied u becomes Determine the average normal B strain developed in wire AC. Originally the cable is unstretched. If a force is applied to the end D of the member and causes a normal strain in the cable of 0. The corners of the square plate are given the displacements indicated. Determine the shear strain along A the edges of the plate at A and B.
The corners B and D of the square plate are given y the displacements indicated. Determine the average normal strains along side AB and diagonal DB. The force P applied at joint D of the square frame causes the frame to sway and form the dashed rhombus. Determine the average normal strain developed in wire AC.
