3. Two people carry a heavy electric motor by placing it on a light board 2.00 m in length. One person lifts at one end with a force of 70ON, and the other lifts the opposite end with a force of 500N. What is the weight of the motor, and where along the board is its center of gravity located? (Note: The center of gravity of an object is the point where the weight passes through.)

Trina is a gym goer with a leg length of 84 cm. Suppose that she is in the gym doing straight leg raising with 10 Ib weights. Compute for the force that the muscle should exert in order to (1) maintain it in the position and (2) lift the weight up given that the distance of the effort (muscle) from the joint is 54 cm, distance of the weight is 80 cm, and the COM is 45 cm from the joint. Questions: 1. Draw the free body diagram for straight leg raise. 2. What is the muscle responsible for straight leg raise? 3. What is the fulcrum? 4. What is the effort? 5. What is the resistance?

Q3: The diagram shows the open bonnet of a car. The bonnet is vertical force V held open at an angle of 60° to the horizontal by a vertical force V applied at one end of the bonnet (shown on the diagram). The car bonnet bonnet is 0.90 m long, has a weight of 25 N and its center of gravity G is 0.35 m from the hinge at O. 0.90m 1) On the diagram, draw and label the two forces other than V acting on the bonnet. 2) By taking moments about O, show that the vertical force V applied at the end of the bonnet is 9.7 N. 60 horizontal hinge O 3) Calculate the magnitude of the force acting at the hinge O.
Diagram of the problem, necessary formulas, clearance and numerical solution It is planned to lift a car with a hydraulic crane. The platform on which the vehicle is is 5,000 cm2 and its mass is 2.5 tons. If the area of the smaller piston is 750 cm2, what must be the force applied to lift the car?
s) A cylinder that is 750 mm in diameter and 2.5 m long has a specific weight of 835 N/m³. It eid down into position with a cable attached to the sea floor. At this location, the sea is 500 m deep and the cylinder is to be held in a fully submerged position just 3 m above the sea floor. Find the resulting tension in the cable.

State Pascal’s principle and give one application of the principle. An object is dropped into a beaker of water. Two forces are operating on the object viz. the weight of object and the buoyant force FB due to the fluid. Explain, in terms of the forces when the object. a.) Sinks to the bottom of the beaker b.)Floats in the water A hydraulic press for compacting powdered samples has a large cylinder with a diameter of 10.0 cm and a small cylinder of diameter 2.0 cm. If a force of 350 N is applied to the small cylinder, what will be the force exerted by the fluid on the large cylinder? Be consistent with your units.
