Shear

Shear walls are another form of vertical structural support that stiffen the design of a structure. They are often placed in open columns within a building such as elevator shafts or staircases. Although shear walls reduce flexibility, sometimes Civil Engineers use moment-resisting frames. These can either be used with shear walls or as a complete substitute for them. Moment-resisting frames which allow the beams…

Over the years, the industries of structural, mechanical, aerospace engineering, materials science, medicine, prosthetics, and many more have called for stronger, lightweight, low maintenance materials to withhold the stresses and loads that come with everyday usage of materials. Material scientists and engineers have studied and manufactured composite materials to cater to the needs of these various industries; however, composites have limitations as well. Many composites need repairs after…

suspension to form a gel network and it is characterized by shear thinning properties. Example, guar gum and xanthan. Particle settling decreases the stiffness of the polymeric matrix, where the particles are trapped. Polymeric chain provide electrostatic or steric stabilization to disperse the particles. Rheological shear thinning properties fine some beneficial in the preparation of suspension and their uses. As viscosity reduces at high shear rate facilities deagglomeration, mixing and flow…

Book: The Curious Incident of the Dog in the Night-time, Mark Haddon, 226 pages Theme: In order for a person to be successful, they need be surrounded by UNDERSTANDING people. To start with, the main character, Christopher, reflects upon first meeting Siobhan eight years ago, “She showed me this picture and I knew that it meant ‘sad,’ which is what I felt when I found the dead dog” (2). Siobhan knows that Chris has a really hard time trying to converse with people because it is hard for him to…

515). The Braden scale measures the risk for the development of a pressure ulcer by using 6 subscales: sensory perception, moisture, activity, mobility, nutrition, and friction/shear (Hyun, 2013). “Each of the subscales is scored from 1 to 4 (1-3 for friction/shear), with 1 representing the highest risk. The summative Braden score ranges from 6 to 23” (Hyun, 2013, p. 515). The lower the total score on the Braden scale the greater the risk for developing a pressure ulcer…

confirm his story for the judge,and jury. Upon hearing a screech, they both go down the hidden staircase to find Nicholas Simmons holding Alma hostage. Kelsey accuses Simmons for killing his aunt and uncle for their money and leaving Kelsey's animal shears behind to frame him.Nicholas Simmons' planned destruction of the house was an effort to destroy the secret staircase that would mess up his alibi. Heggs rescues Alma by hitting Simmons unconscious with a punch from behind. Nicholas Simmons is…

km/h). However, the storm weakened back to a Category 3 hurricane several hours later due to increasing vertical wind shear.[29] At 15:00 UTC on October 13, the hurricane's eye passed directly over Bermuda, where automated surface station measured sustained winds of 87 mph (141 km/h) and a gust reaching 119 mph (191 km/h).[117] At 06:00 UTC on October 14, southwesterly wind shear reduced the system to Category 1 status. The storm slowly began to weaken the next day, falling to a tropical storm…

• Reciprocating motions (back and forth or up and down) – employees can be struck by or caught between moving and stationary parts • Transverse motions (movements in straight, continuous lines) – employees can be struck by or caught in pinches or shear points by moving parts Ask: What are the main types of action hazards? Listen to responses. Show PowerPoint Slide #10, “Action Hazards.” • Cutting action • Punching action • Shearing action • Bending action Explain that: • Cutting action involves…

Typhoon Haiyan – Vulnerabilities and Resiliency in the Philippines On November 8th, 2013, the Philippines faced a disaster with tremendous impact. Typhoon Haiyan was a devastating super storm that affected the islands of the Philippines, especially Tacloban city. According to Barmania (2014) the typhoon, that had wind speeds around 150 mph, killed 6200 and displaced 4 million people, leaving the country in despair. Characteristics of typhoon Haiyan and Tacloban City: The characteristics of…

were measured at around 38 mph, and the NHC upgraded the storm from a tropical depression to a tropical storm. (Stewart, 2014). The tropical storm was named Arthur. Arthur was “expected to be in an environment of light northwesterly vertical wind shear for [the following] 60-72 hours.” (Bevan, 2014). The forecast called for Tropical Storm Arthur to “become a hurricane in about 36…
