Answer: part a) both the tension and gravity vectors will be pointing downwards.
part b) the tension vector will be pointing upwards and the gravity will be pointing downwards.
Explanation:
part a) Since you are looking at the FBD for the steel cable here, the tension will be pointing downwards because the girder is hung from the cable which creates a downwards tension. Gravity will always point downwards, to the ground.
part b) Since you are looking at the FBD for the girder here, the tension will be pulled upwards because the cable is weighted which creates an upwards tension. Gravity will always point downwards, to the ground.
Sorry for the poor explanation, but hopefully this makes sense.
(a)Both the tension and gravity vectors will be pointing downwards in the component.
(b) The tension vector will point upwards, whereas the gravity vector will point downwards.
A free-body diagram is a diagrammatic representation of a single body or a subsystem of bodies that have been isolated from their surroundings and depicts all of the forces acting on it.
(a) Both the tension and gravity vectors will be pointing downwards in the component.
Because the girder is suspended from the cable, creating downward tension. Gravity will constantly pull you down, toward the ground.
(b) The tension vector will point upwards, whereas the gravity vector will point downwards.
The tension will be lifted upwards due to the cable's weight, which causes upwards tension. Gravity will constantly pull you down toward the ground.
Hence the tension and gravity is shown with the help of FBD in both cases
