Does the size of a paper airplane affect how far it flies

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

True or false graphs must include scales that increase by the same amount
