two sides’ perpendicular to the radius of a uniform cross-sectional bar. To study the response of materials under a torsional force‚ the torsion test is performed by mounting the specimen onto a torsion testing machine‚ then applying the twisting moment till failure. The torque and degree of rotation are measured and plotted. It can be seen higher torsion force is required at higher degree of rotation. Normally the test specimens used are of a cylindrical rod type since the stress distribution across

Danielle Zimmerman Professor Mable Weatherby English 111 03/24/13 In a Common Tavern Response Paper Audience Analysis My target audience will be my classmates and my professor. Unfortunately‚ I don’t know any of these people personally‚ so I would have to be broad and unspecific when describing them. I know that we have all read the same material‚ so we have that. I hope that my audience‚ especially my professor‚ has experience with poetry. Whether that is from taking English

energy = mgh‚ is equal to the (1) Gain in kinetic energy = 0.5mv2 + 0.5I 2 (2) where v = velocity of the mass centre down slope (m/sec) = angular velocity of wheel (rad/sec) = v/r‚ r is the axle radius when rolling I = Polar moment of inertia = mR2/2 Applying conservation of energy‚ equate equations 1 and 2 to derive an expression for the velocity v at the bottom of the slope. Using the linear equations of motion‚ find the expression for time t. Show these derivations in

acting irrationally. My friends would always do things with spontaneity while I would get left behind sitting alone shrouded by my fear. As life gradually moved on‚ I grew to overcome my fears and not overanalyze situations with the help of a few moments in my life. One event I remember with startling clarity was when I was seven. Like many children‚ my brother and cousins loved to ride roller coasters and enjoyed the thrill that accompanied it. However‚ I never relished the execrable feeling of

A Small Moment in Time An influential person in my life that made me rethink everything I was doing was my 4th grade teacher. In lower grades I was always advanced‚ and I knew more about everything than everyone else. In kindergarten I was put in a class to test my advancement for a year. Then after that year of testing I was offered to skip 1st through 3rd grade as long as I did summer math advancement help. My mom declined the advancement wanting me to be put with children my age‚ but this is
