The person in Figure P4.51 weighs 190 lb. Each crutch makes an angle of = 22.0° with the vertical.
Half of the person's weight is supported by the crutches, the other half by the vertical forces exerted by the ground on his feet.
Assuming the person is at rest and the force exerted by the ground on the crutches acts along the crutches, determine each of the following.

1.) the smallest possible coefficient of friction between crutches and ground

2.) the magnitude of the compression force supported by each crutch

Objects of masses m1 = 4.00 kg and m2 = 9.00 kg are connected by a light string that passes over a frictionless pulley as in Figure P4.48. The object m1 is held at rest on the floor, and m2 rests on a fixed incline of = 40.0°. The objects are released from rest, and m2 slides 1.50 m down the incline in 4.30 s.

a.)Determine the acceleration of each object

m1 upward and m2 down the incline

b.) Determine the tension in the string.

c.) Determine the coefficient of kinetic friction between m2 and the incline

I'm in my first real design class and I have to create a simple processor in VHDL and implement it on a FGPA board later on. I'm designing the ALU right now and I would like to know what's the purpose of having a multiplexer implemented with the adder-*** -subtractor? If you know of a website that offers schematics so that I can actually see where they are that'd be great as well (googling hasn't been rewarding as of yet) .Maybe if I knew what a multiplexer does to help a ACS I'd actually be able to design it..thanks guys!
