67 g bullet moving horizontally hits a 4.1 kg block resting on a rough horizontal table. If the bullet remains embedded in the block and the combination slides 7 m before coming to rest, find the velocity of the let. Assume the coefficient of friction between the block and the table is 0.2.

It is designed in such a way that the internal temperature of a commercial heat treatment furnace can reach up to 165 oC. All surfaces of the furnace consist of firebrick (10 cm), insulation material and sheet metal (3mm) from the inside out. Given that the outdoor temperature is 22 oC, the outer sheet will be allowed to go up to 35 oC, which is a temperature that will not disturb in contact with hands. In this case, determine the insulation material thickness to be used. The thermal conductivity coefficient of the insulation material is insulation 0.066 W / m oC, 60 W / m oC for sheet metal and 115 W / m oC for firebrick. Indoor heat transfer coefficient will be accepted as 25 W / m2 oC and 12 W / m2 oC for outdoor environment.

Item 1 used to intermittently operate a piece of equipment at the end of a lifter arm. The lifter is in contact with the highest point of the cam at the instant shown and the lifter is constrained to move only in the vertical direction. The cam has a radius of r = 4.5 in and is rotating about point O, which is offset from the center by a distance c = 3.0 in. The cam's angular position is measured from the positive x axis and is positive clockwise. The angular velocity and acceleration are positive clockwise.

A left hand threaded 14 mm diameter A36 steel bolt is stuck in a metal block. Assume the bolt head is flush with the block surface at A. In order to remove the bolt the 50 Nm torque is applied to the bolt head as shown. The block applies a resisting torque "t" to the stuck threads which is assumed to be uniformly distributed along the 50 mm buried depth. G = 75 GPa a) Explain the difference between right and left hand threaded bolts Determine: b) The magnitude of the uniform resisting torque "t" (including proper units) c) The internal torque as a function of x measured from B (a FBD is required) d) The maximum shear stress in the bolt Ans: 92.8 MPa e) The angle of twist of bolt head A with respect to end B Ans: 0.0044 rad f) The largest torque that can be applied to the bolt head before it twists off (Tyield = 150 MPa) %3D
