1. For the typical Oar (shown in the figure below) used in rowing boats, select an engineering material that would be lightweight and stiff. It must be strong enough to carry the bending moment exerted by the rower without breaking and it must have the right stiffness. The function is identified to be a beam, loaded in bending. The length L and stiffness S are fixed by the design, leaving the radius R as the only dimensional variable. The mass m of the oar is minimized by choosing materials with large values of the material index. E1/2 M1 %3D

1. a) Define a holonomic constraint and explain the impact of such constraints on the number of degrees of freedom of a system. Give an example of a non-holonomic constraint. b) Five identical flat circular plates are served on a circular conveyor belt. The plates have mass m, radius 5 cm and moment of inertia Ip about their axis of symmetry. They are free to move under gravity on top of a conveyor belt which has inner radius a, outer radius b and moment of inertia Ic about a vertical axis through its centre. From above, it looks like the diagram below. a The belt is banked at a fixed angle a such that the inner edge is lower than the outer edge. Assuming the conveyor belt rotates freely, how many degrees of freedom does this system have? Find the Lagrangian for the system. Hence find and identify any conserved quanti- ties of the system. 1 1

Hanging from the ceiling over a baby bed, well out of baby’s reach, is a string with plastic shapes, as shown here. The string is taut (there is no slack), as shown by the straight segments. Each plastic shape has the same mass m, and they are equally spaced by a distance d, as shown. The angles labeled θ describe the angle formed by the end of the string and the ceiling at each end. The center length of sting is horizontal. The remaining two segments each form an angle with the horizontal, labeled ϕ . Let T1 be the tension in the leftmost section of the string, T2 be the tension in the section adjacent to it, and T3 be the tension in the horizontal segment. (a) Find an equation for the tension in each section of the string in terms of the variables m, g, and θ . (b) Find the angle ϕ in terms of the angle θ . (c) If θ = 5.10° , what is the value of ϕ ?
