o please anser 1 and 2 and 3 please please

1. An object is pivoted about a fixed point located along the z-axis. The driving force is given by N. Suppose the force is applied at a point located at , determine the torque due to this force. 2. A seesaw in a children's playground is 4.00 m long pivoted at its center. Suppose a 25-kg child sits at one end of the board, where should a 35-kg child sit to balance the seesaw? 3. Consider the system shown. A 5.00 m beam supports a mass of 3000 kg attached to a cable. The mass of the beam is 1000 kg. Assume that the mass of the beam is uniformly distributed throughout its length. (a) Determine the tension in the cable (b) Calculate the horizontal and vertical components of the force exerted at point O. 5.00m 3000 kg 45.0°
