MATHalino Now Offers Online Courses

No, this is not an announcement or promotional post. This is about my experience in building the platform for online courses.


Creating an online course is monumental specially to small websites like MATHalino. Despite being manned by one person from the ground up, the development of this functionality is actually progressing by degrees. I've been conceiving this feature as far as I can recall, way before online courses become a common thing in the Philippines. What makes me unable to implement it before comes from three factors.

The solid pole shown in the figure is loaded with a vertical load P = 25 kN and lateral load H = 0.95 kN. The pole is 3 m high, 300 mm diameter and weighs 22 kN/m3.



The area of a park on a map is 600 mm2. If the scale of the map is 1 to 40,000 determine the true area of the park in hectares (1 hectare = 104 m2).

A.   112 C.   96
B.   84 D.   120


The three-hinged arch shown below is loaded with symmetrically placed concentrated loads as shown in the figure below.



The loads are as follows:
$$P_1 = 90 ~ \text{kN} \qquad P_2 = 240 ~ \text{kN}$$

The dimensions are:
$$H = 8 ~ \text{m} \qquad S = 4 ~ \text{kN}$$
