1. A uniform ladder weighing 200N leans against a wall as in Fig 1. The forces on the ladder are W (vertically downwards), Fw (horizontal) and Fg (at an angle of 60° to the horizontal).

(a)
Consider there is no friction between the wall and the top of the ladder, draw a diagram to represent the forces on the ladder.

(b) Calculate the friction force Fh (horizontal force on the foot of the ladder) from the floor.

(c) Calculate the normal reaction Fv (vertical force on the foot of the ladder) from the floor.

(d) Calculate the resultant force from the ground Fg and its angle, θ, to the vertical.

(e) Calculate Fw (the reaction from the wall).
