Wooden Block Lab Report

For this experiment, the very first step is to weigh the plain block and object used on top of the wooden block in grams and Newton’s, as this information will be useful throughout the lab. Next place the ramp board horizontally on a table to measure the friction of the block and the weight of the soft drink can set on top of the wooden black by connecting the blocks hook to the spring scale. Meanwhile set the block and its weight on the board with its largest surfaces in contact with the surface of the board and connect the blocks hook to the 500-gram spring scale. Using the spring scale, slowly pull the block from rest. When the block just begins to move the force indicated on the scaled should be recorded. This requires more force and is approximately equal to the static frictional force. Repeat two more times.
Prepare up to six data tables to record the following information: mass and weight of the plain block, Force of kinetic friction and force of static friction in Newton’s throughout the experiment, height and base in the last table, also calculating the limiting angle of repose θ max and Static friction force by dividing the height by the base of your incline for the last table.
Essentially, you will perform 18 different trials over the course of this experiment and then calculate the average of your trials for each table. Now we turn the wood block to its side, repeating the entire process from part 1 above three more times and record the force the kinetic and static friction for each trial.

After part 2, it is also necessary to determine the force of static and kinetic friction for the other surfaces that come with the lab kit, which are the mirrored and sandpaper surfaces. Try using the blocks provided with at least two flat surfaces around the home to understand the concepts learned in the previous parts of this lab, such as carpet, rubber, tile, or anything similar. Record your results in the tables similar to data table
3.

Finally place the plain block with its greatest surface in contact on the board while the board is lying flat. Gradually raise one end of wooden block until it begins to slide down. Acquire the exact value of the angle with the horizontal at which the block breaks away, providing that this would be the limiting angle of repose. Consequently measure it with a protractor and record the results, but do not forget to also measure the base and height of the triangle formed by the board. Remember the height divided by the length of the base equals the coefficient of static friction measurement. Perform two more trials to finish the experiment.
