The following PhysCast deals with a non-uniform bar which is suspended and in static equilibrium. A nonuniform bar is suspended at rest in a horizontal position by two massless cords. One cord makes the angle theta = 36.9 degrees with the vertical; the other makes the angle phi = 53.1 degrees with the vertical. If the length of the bar is 6.10 m, compute the distance x from the left end of the bar to its centre of mass.

This is a PhysCast on 2 dimensional motion. A raging flood has washed away a section of highway, creating a gash 1.7 meters deep. A car moving at 31 m/s goes straight over the edge. How far from the edge of the washout does it land?

In this problem we will be looking at the difference between doing a vector calculation and a scalar calculation. A ball moving horizontally at 20 m/s bounces off a wall, and then moves at 10 m/s in the opposite direction. What is the ball's change in velocity and change in speed?

This PhysCast deals with a problem involving 1 dimensional motion. A ball is thrown straight upwards and reaches a maximum height of 5.2 m. (a) What was the ball's initial speed? (b) How long did it take for the ball to reach the top of it's flight?

This question deals with both hydrostatics and hydrodynamics. A 4.0cm diameter horizontal pipe connects passes through a freshwater dam at a depth of 6.0 meters and is sealed by a plug. A) Find the magnitude of the frictional force between a plug and the pipe wall? B) With the plug removed what volume of water exits the pipe in 3.0h?

This problem is about Newton's 2nd Law. A lift cable can withstand a tension of 18,000N before snapping. The empty lift has a mass of 500kg and the maximum acceleration of the lift is 2.25 m/s2. If safety regulation state that the cable should never experience a force greater then two thirds of its breaking tension, how many 65kg people can safely travel in the lift.

This problem is about simple harmonic motion. A Grandfather clock contains a ball with a diameter of 5 cm suspended from a light, inextensible wire. A modern clock has a think metal rod instead of a ball and wire. Both clock tick when the pendulum reaches its maximum displacement. How long must the wire and rod be if the clocks are to tick ever second exactly?

This PhysCast is going to deal with a problem that has a block being pulled up a ramp and how we can apply Newton's 2nd Law to analyse it. A 14.0 kg block is pulled up a frictionless ramp by a 70.0 N force parallel to the ramp. The ramp is inclined at 25 degrees to the horizontal. If the block is initially stationaly, how far does it move in the first 3.0 seconds?

This problem involves work done by constant forces, including friction. A 40 kg box is pushed 5.0 metres along a rough horizontal floor with a constant applied force of 130 N. The co-efficient of kinetic friction between box and floor is 0.30. What is the total work done on the box.

This PhysCast will go through some basics of using vectors.
