The a-36 steel bolt is tightened within a hole so that the reactive torque on the shank ab can be expressed by the equation t = (kx2) n. m/m, where x is in meters. if a torque of t = 50 n. m is applied to the bolt head, determine the constant k and the amount of twist in the 50-mm length of the shank. assume the shank has a constant radius of 4 mm. the shear modulus of elasticity for a-36 steel is 75 gpa.

What is the order of the moon, earth, and sun in a lunar eclipse and a solar eclipse?

When considering gravity acceleration and the force of acceleration, what must be true? a. the direction of acceleration must be perpendicular to the direction of the force. b. the direction of the force and the direction of acceleration must be the same as each other. c. the direction of the force and the direction of acceleration must be opposite of each other. d. the mass of the body must be the same as the acceleration of the body.

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.
