PIÑ PHYS 1455

Piñata Physics:

Objectives: To understand, develop and apply the mechanics and dynamics involved in positioning and breaking a typical mexican piñata. At the end of this course, the student will be able to know how to efficiently swing and break a piñata; able to calculate the speed, force, torque, yaw, roll and swing of the piñata. The student will be able to calculate the modulus of elasticity and what is the effect of a perfect impact.

Required Material for class: Rope, Bat and “Make your own piñata kit”.

Lab: once per week

Required Material for Lab: Bowl, Chips, Salsa and a big Mexican Hat.

Prerequisites: Students should have successfully passed SALS 101 (Introduction to Salsa making and catering), ENG 1009 (Introduction to beer drinking) and regular engineering stuff.

Professor: Grajeda, G.

Matrix Multiplication… easy way

I had a vision. I should share my discovery with you mortals…

|A  C|   |E   F|     =   |A·E + C·G        A·F + C·H|

|B  D|   |G  H|    =    |B·E + D·G       B·F + D·H|

And now that you know how to multiply your matrices in a simple way. Share it with the world, because my teacher didn’t do it and I had to come with a self explanation although it was obvious for any geniuses out there… but not me! That’s why I share this with you mortals!
