In a simple jib crane, the vertical post is 2.4 m high, the jib is 3.9 metres long and the tie 2.1 metres long. Find the forces on the jib and tie rod when a weight of 2.5 kN is supported at the crane end.

Using software, a simulation of a javelin being thrown both on earth and on the moon is created. in both cases, the velocity and angle of projection are kept the same. on earth, the javelin covers a distance y. what distance would it cover on the moon? (the moon’s gravity is about 1/6th that of earth.) a. 6y b. 6/y c. y/6 d. (y+6)2
