were seriously injured. This accident occurred because the braking system was not properly designed. Operation of the brake over its lifetime produced higher than estimated bending forces on the system and induced fluctuating stresses on the braking rod that it could not sustain. Crack propagation developed in the rod due to bending stresses and eventually extended until fracture occurred‚ sending the cage of men to the bottom of the shaft at nearly 30 miles per hour.

DOI: 9/4/2014. The patient is a 40-year old male carpenter who sustained a work-related injury to his low back and left shoulder after lifting a heavy beam at work. Patient is status post lumbar ESI at L5-S1 per procedure report dated 05/13/15. Per the PT daily treatment note dated 0/09/14‚ the IW has attended 6 sessions for the back. Per the AME done on 11/13/15 by Dr. Warbritton‚ Whole Person Impairment (WPI) rating for the back is 8%. Future medical care includes independent strengthening

CHAPTER 1 INTRODUCTION The seismic force-resisting system of a building structure is composed of vertical elements‚ horizontal elements‚ and the foundation (Fig.1.1). The vertical elements extend between the foundation and the elevated levels‚ providing a continuous load path to transmit gravity and seismic forces from the upper levels to the foundation. The horizontal elements typically consist of diaphragms‚ including collectors. Diaphragms transmit inertial forces from the floor system to the

Light I | | INTRODUCTION | Light‚ form of energy visible to the human eye that is radiated by moving charged particles. Light from the Sun provides the energy needed for plant growth. Plants convert the energy in sunlight into storable chemical form through a process called photosynthesis. Petroleum‚ coal‚ and natural gas are the remains of plants that lived millions of years ago‚ and the energy these fuels release when they burn is the chemical energy converted from sunlight. When animals digest

limited because their usage depends on the accompany with the other material. Steel framed structures are designed with the connections between the separate members treated as either non-rigid or fully rigid joints. The frame consists of horizontal beams in both direction and vertical columns called stanchions‚ usually all standard rolled sections of various sizes‚ joined together by welding or by bolts with cleats to form a stiff to which the feet of the stanchions are bolted. All the steel members

SE21 p36-42 Ji 29/10/03 3:42 pm Page 36 paper: ji Concepts for designing stiffer structures Synopsis The paper demonstrates concepts for designing stiffer structures. They are: (a) the more direct the internal force path‚ the stiffer the structure; (b) the more uniform the internal force distribution‚ the stiffer the structure; and (c) the smaller the internal forces‚ the stiffer the structure. These concepts are applicable to the design of many structures. Two ways of implementing
