The mirror housing of the telescope is supported by a 6-bar space truss. the mass of the housing is 3 mg (megagrams), and its weight acts at g. the distance from the axis of the telescope to points a, b, and c is 1 m, and the distance from the axis to points d, e, and f is 2.5 m. if the telescope axis is vertical what are the axial forces in the members of the truss?

F500 j of energy were added to 1 kg of each of these samples, which would experience the least temperature increase?

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
