Question

the object ofthis pre-lab is to use a force table to balance one or more forces using another force or by using compenents. The force table consists of a circlar platform with markings at the edge showing the angle for a circle centered about the center of the table. A mass, m=155 g is placed on a hanger which has a mass of 50g, giving a total mass 205g. The hanger is then hung at an angle of 110 deg over a pully attached to the force table by using a string of negligible mass. The pulley over which the string rests has very low frictional force.

What is the tension, F, in the string?

What are the components of the vector F? The +x and +y axes are at 0 deg and at 90 deg respectively.

Fx=

Fy=

Explanation / Answer

Fx = T(tension in string ) cos(110) = -mg sin(20) -0.687 N;

Fy = T SIn(110) = mg cos(20) = 1.89 N;
