Two supports, made of the same material and initially of equal length, are 2.5m apart. A stiff board with a length of 5m and a mass of 17kg is placed on the supports, with one support at the left end and the other at the midpoint. A block is placed on the board a distance of 1.1m from left end. As a result the board is horizontal (that is, the downward force on each support is the same). The mass of the block is .. kg, to two decimal places. ......

. A tightly stretched horizontal “high wire” is 36 m long. Itsags vertically 2.1 m when a 60.0-kg tightrope walker standsat its center. What is the tension in the wire? Is it possibleto increase the tension in the wire so that there is no sag?
From the step ladder shown in the figure, sides AC and CE are each 2.44 m long and hinged at point C. Bar BD is a tie-rod 0.762 m long, halfway up. A man weighing 845 N climbs 1.8 m along the ladder. Assuming the floor is frictionless and neglecting the mass of the ladder, find the tension (in N) in the tie-rod.
