The copper pipe has an outer diameter of 40mm and an inner diameter of 37mm. if it is attached to the wall at point a and three torques are applied as shown, determine the minimum shear stress developed in the pipe. answers should be given in units of mpa.

Consider motion in one dimension. (the sign of the vector quantities is their direction indicator.) an object moves in the positive x-direction with speed 2.9 m/s for 4.5 s. it stops for 3.8 s and then moves in the negative x direction with speed 2.8 m/s for 4 s. what is the total distance traveled by the object in units of meter? enter a number with two digits behind the decimal point.
