Example: A 0.300 kg mass rests on a 0.395 m long, 0.764 kg, uniform wooden plank supported by a string as shown in the figure. If the mass is 0.274 m from the wall and the angle between the string and the plank is 32.1°, (a) What is the force of tension in the string? and (b) What is the normal force from the wall?

Torque: It makes things rotate
pavelow posted a blog entry in Blog Having Nothing to do with Physics
Torque is the tendency of force to rotate something around an axis. Torque helps you turn a doorknob, it makes a car's tires spin, it basically helps a force act in a circle. Applications of torque equations can help solve real world problems. Locations for supports for bridges can be determined by examining the effects of the torque vehicles would cause on a bridge. An engineer looking to efficiently maximize the potential for producing torque in an engine would choose electrical or diesel power over gasoline power to use the fuel effectively. People who would like to easily compare 
So senior year has finally come to an end and we all are saying goodbye. So I thought I would discuss the physics of senior year. The year has had so much physics enwrapped in it, in and outside the classroom. We got to use physics in physics c (duh), calculus, and technology for those who take these classes. With a basic understanding of physics, these classes became easier to learn and master. Outside the classroom, physics was used by every athlete in the school in some shape or form from lacrosse involving torque, to hockey with rotational motion. But there is so much more. Physics was us

Objective: Moment of Inertia by Inquiry Description: Students experimentally determine the moment of inertia of six different objects (2 solid spheres, 2 solid discs, and 2 rings) by rolling them down a ramp. They then compare their experimentally determined values to the theoretical values which they calculate themselves. Equipment: 2 solid spheres 2 solid discs 2 rings (note that these items can be purchased as a group set through lab supply vendors, or you may create your own) stopwatch meter stick protractor string Procedure: Students develop their own procedures for thiFree
