The uniform hatch door, having a mass of 15 kg and a mass center at g, is supported in the horizontal plane by bearings at a and b. if a vertical force f = 300 n is applied to the door as shown, determine the components of reaction at the bearings and the angular acceleration of the door. the bearing at a will resist a component of force in the y direction, whereas the bearing at b will not. for the calculation, assume the door to be a thin plate and neglect the size of each bearing. the door is originally at rest.

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.
