Hi there! i have this question about turning forces and i'm a bit confused with the centre of mass and pivot question.

jic the pic cant be seen:
a uniform metre ruler pq is in equilibrium.
the distance pq is 100cm
the mass of the metre ruler is 0.12kg and its weight is w.
point p is 10cm from the pivot and has a weight of 0.5n hanging from it. point q has a force going upwards on it.

question: on the fig. draw
1. an arrow to shoe force w acting in pq at the centre of mass
2. an arrow to show the force r acting at the pivot.

Aturntable a is built into a stage for use in a theatrical production. it is observed during a rehearsal that a trunk b starts to slide on the turntable 10 s after the turntable begins to rotate. knowing that the trunk undergoes a constant tangential acceleration of 0.31 m/s2, determine the coefficient of static friction between the trunk and the turntable.
