Problem 3: A bent beam ABCD is held in equilibrium by a roller at A and by a pinned connection at D. The beam supports a uniform distributed load (80 lb/ft) over section AB and a concentrated force (390 lb) at point C. The roller at A rests against an inclined surface that is oriented 30° from the horizontal direction. Neglect the weight and depth of the beam and the size of the roller in this analysis.

The Straw Hat crew on their journey to Laugh Tale Island found a big treasure box (W). Luffy wanted to place the treasure box (W) as shown in the figure. A 100-mm x 300 mm rectangular beam is supported in a horizontal position. At point "A", it is being held by a pin and at "B" by a cable BD inclined 3 vertical to 4 horizontal. Assume all forces are applied to the beam along its central axis. Given that Fcparallel to grain = 10.50 MPa, W = 79 kN and E = 13800 MPa. Neglecting the weight of the beam and cable, determine whether the design is safe. Cable 2.4 m 2.4 m
Problem 4.30 While the stiffness of an elastic cord can be quite constant (i.e., the force versus displace- ment curve is a straight line) over a large range of stretch, as a bungee cord is stretched, it softens; that is, the cord tends to get less stiff as it gets longer. Assuming a soften- ing force-displacement relation of the form k8 - B83, where 8 (measured in ft) is the displacement of the cord from its unstretched length, considering a bungee cord whose unstretched length is 150 ft, and letting k = 2.58 lb/ft, determine the value of the con- stant B such that a bungee jumper weighing 170 lb and starting from rest gets to the bottom of a 400 ft tower with zero speed.
