Unformatted text preview: TAM206 Spring semester 2001. Quiz No.1 Name ...................................... .. Q.1 The uniform beam AB carrying the man
and load is supported at each end by two ropes as
shown. The pulley weighs 15 lbs, the beam weighs
60 lbs, the man weighs 160 lbs and the system is in
equilibrium. (a) Draw the freebody diagram (FBD)
for the man on the beam AB showing all forces on
him and write down the detailed equilibrium
equations (10 pts). (b) Draw the free—body diagram
(FBD) for the beam AB showing all forces on it
and write down the detailed equilibrium equations
(10 pts) (0) Find the forces in the ropes at A
assuming both ropes carry equal loads (10 pts). TAM206 Spring semester 2001. Quiz No.1 Name .................................... .. Q2. A 250 lb roller is to be moved over the step
by applying a force P as shown. (a) Draw an appropriate FBD when the roller is
just on the point of lifting of the lower surface. (10
pts) and (b) using the equilibrium equations, calculate the
force P required to move the roller. (10 pts) (c) Determine the reaction components acting on
the step. (10 pts) ((1) Would the force P become lower if the line of
action of P was horizontal? Give clear reasons(10 pts) TAM206 Spring semester 2001. Quiz No.1 Name .................................... .. Q3. A force of magnitude 850 N acts at a point
A as shown. (a) Determine the moment of the force about point
B. (10 pts) (b) If a force of equal magnitude and opposite
direction acted at B, what would be the moment of
the resulting couple about 0? (10 pts) (0) What is the resulting moment about the XaXis? (10 pts) ...
