A spring loaded valve is to be used for operation of compressed air. The valve seat is 10 mm in radius. When the pressure on the valve reaches 1.05 N/mm2, its opening starts and when the pressure reaches 1.4 N/mm2, the valve must be completely open. During the operative pressure range, the valve lift is 6 mm. The steel used for the spring material has yield strength of 2000 MPa, and a shear modulus of 85 kN/mm2. Design the spring assuming appropriate data, if deemed necessary.

A spring-loaded dart gun is used to shoot a dart straight up into the air, and the dart reaches a maximum height of 19,79 meters above its point of release. The same dart is shot up a second time from the same gun, but this time the spring is compressed only half as far (compared to the first shot). How far up does the dart go this time? (Neglect friction and assume the spring is ideal and massless.) Answer in...

A spring-loaded toy gun is used to shoot a ball of mass m=1.50 kg straight up in the air
A spring-loaded toy gun is used to shoot a ball of mass m=1.50 kg straight up in the air, as shown in (Figur 1) . The spring has spring constant k =667 N/m. If the spring is compressed distance of 25.0 centimeters from its equilbriurn position y = 0 and then released, the ball reaches a maximum height hax (measured from the equilibrium position of the spring). There is no air resistance, and the ball never touches the inside of...
