Ql: Determine the x- andl-coordinates of the centroid

of the shaded area. (25Mark)

Q2: Calculate the forces in members BC, BE, and EF.

Solve for each force from an equilibrium equation

which contains that force as the only unknown. (25Mark)

Q3: Calculate the x- and y-components of the force C which member

BC exerts on member ACD. The cables are wrapped securely around

The two pulleys, which are fastened together (25Mark)

Q4: Determine the distance H from the bottom of the base to the

mass center of the bracket casting. (25Mark)

Q5: The light cable supports a mass of 30 kg per meter of horizontal

length and is suspended between the two points on the same level

300 m apart.If the sag is 60 m, flnd the tension at midlength, the

maximum tension, and the total length of the cable. (25Mark)
