(13%) Problem 5: A shop sign weighing m;g hangs from one end of a uniform beam weighing mpg. A hinge attaches the other end of the beam to a wall. The beam has a length of l1. A cable is attached to the beam a distance l2 from the hinge to help support the beam. The cable makes an angle 0 with the beam as shown. e 4 Paul's o o. Auto Repair E A 13% Part (a) On the following free body diagram, draw all of the forces acting on the beam, representing the forces as vectors. Use a coordinate systen with the x-axis on the horizontal (along the length of the beam) and the y-axis vertical (perpendicular to the beam). Use "wb" for the weight of the beam, "ws" for the weight of the sign, "FT" for the force of tension, and "H" for the force on the hinge. Finally, since we don't know the angle that the force on the hinge will act based on the diagram alone, let it be acting at an angle be denoted "o" from the positive y-axis.

H.W: Design a knuckle joint for a tie rod of a circular section to sustain a maximum pull of 70 kN. The ultimate strength of the material of the rod against tearing is 420 MPa. The ultimate tensile and shearing strength of the pin material are 510 MPa and 396 MPa respectively. Determine the tie rod section and pin section. Take factor of safety = 6.

(5) A gas engine valve spring is loaded to 35kgf when the valve is closed & 52kgf hen the valve is open. The valve lift is 8mm. The outside diameter is to be from 38mm~45mm, & the permissible stress is 413N/mm2 . Determine: (a) the wire & outside diameter; (b) the number of effective coils; (c) the free length when it is squared & ground.
Problem 1 The SERO CHIENS C is recreating rolling large stone columns by animal power and pivot points cut into the center of each of the column. The friction in each pivot point plus the rolling resistance creates a resisting couple of 300 ft*lb (like a rusty bearing). The yoke angle B = 10°. a) Determine how many horses (i.e. horsepower https://en.wikipedia.org/wiki/Horsepower) they need to move a 4600-lb column that is 10 ft long and 2 ft in diameter up a 0 = 5° slope from rest to 3 miles per hour after 15 feet of travel. b) Determine how many horses they need to maintain a constant speed of 3 mph up the slope. Round your answers up to the nearest integer. A fraction of horse doesn't pull very well. Assume the column rolls without slipping.
