a child weighing 25 kg is standing on the ball of her foot. The total length of her foot (heel bone to the great toe) is 23 cm, the distance between the great toe and the ball of her foot is 4 cm and the distance between her Achilles tendon and her ankle joint is 5 cm. Calculate the forces on her tibia and her Achilles tendon. Which force is tensile and which is compressive? [Acceleration due to gravity, g, is 9.81 ms -2]

A uniform horizontal strut weighs 400.0 N. One end of the strut is attached to a hinged support the wall and the other end of the strut is attached to a sign that weighs 200.0 N The strut is also supported by a cable attached between the end of the strut and the wall. Assuming that the entire weight of the sign is attached at the very end of the s find the tension in the cable and the force at the hinge of the strut.
